Abstract:

Bismuth oxide with its unique narrow bandgap has gained significant attention in the field of photocatalysis. A new and efficient method to synthesise bismuth oxide with tuneable properties is proposed herein. A surfactant assisted modified sol–gel method is used to synthesise bismuth oxide with excellent photocatalytic activity for the degradation of Rhodamine B dye. Three different surfactants, namely polyethylene glycol-400, sodium lauryl sulfate, and cetyltrimethylammonium bromide (CTAB) have been used. The fabricated bismuth oxide nanoparticles were characterised by X-ray diffraction, IR, scanning electron microscopy, and UV-diffuse reflectance spectroscopy analysis. Evolution of both the α and β crystalline phases of bismuth oxide was observed. The bandgap of the synthesised bismuth oxides ranges from 2.03 to 2.37eV. The CTAB assisted synthesised bismuth oxide with a bandgap of 2.19eV showed the highest photocatalytic activity of 93.6% under visible light for the degradation of Rhodamine B. This bismuth oxide based catalyst opens a new avenue for efficient photocatalysis for environmental remediation.

Abstract:

In this review, we reported the main achievements reached by using bismuth oxides and related materials for biological applications. We overviewed the complex chemical behavior of bismuth during the transformation of its compounds to oxide and bismuth oxide phase transitions. Afterward, we summarized the more relevant studies regrouped into three categories based on the use of bismuth species: (i) active drugs, (ii) diagnostic and (iii) theragnostic. We hope to provide a complete overview of the great potential of bismuth oxides in biological environments.

Abstract:

Bismuth titanate is a typical layer-structured ferroelectric material and belongs to the Aurivilius type-structure compounds family. A bismuth titanate ceramic material could be obtained by mechanically activated synthesis after thermal treatment at a temperature slightly lower than in conventional solid-state reaction. In this case bismuth titanate was prepared through mechanochemical synthesis starting from bismuth oxide and titanium oxide in rutile form. The mixture of oxides was milled in a zirconium oxide jar in a planetary ball-mill in intervals from 1 to 12 hours. The ratio of powders to zirconium oxide balls during milling was 1:20. Bismuth titanate was formed after 1 h. The Raman spectroscopy analysis was performed.

Abstract:

Single phase and ultrafine bismuth oxide was synthesized via microwave-assisted hydrothermal synthesis. The effect of reaction parameters (temperature/pressure and pH) on the product phase composition and morphology was discussed. The transformation of bismuth hydroxide into bismuth oxide was controlled by pH value and it was accelerated by time and temperature. The phase composition of reaction products was strongly dependent on pH value. The amorphous products were obtained at acidic pH conditions and the crystalline single phase product ?-Bi2O3 phase was obtained at pH ?12. The particle size was reduced from micrometric to nanometric size in the presence of a chelating agent. The bismuth hydroxides into bismuth oxides transformation mechanism, consisting in polycondensation of Bi - OH bounds to Bi-O-Bi bridges and crystallization of Bi2O3, was proposed.

Abstract:

Iron oxide and bismuth oxide powder are synthesized by the liquid phase precipitation method. Then a certain proportion of iron oxide, bismuth oxide and sodium chloride are mixed and ground to prepare the bismuth ferrite precursor by the molten salt method. The bismuth ferrite precursors are calcined at different temperatures to obtain bismuth ferrite photocatalyst. By studying the degradation performance of bismuth oxide, iron oxide and bismuth ferrite photocatalysts for methyl orange dyes, the best conditions for the degradation of methyl orange dyes by bismuth ferrite photocatalysts are found. The experimental results show that the bismuth ferrite prepared by calcining at 750°C has the best degradation. Compared with a single oxide, the photocatalytic performance of bismuth ferrite is better.

Abstract:

In this work, we substantiate and develop a general pyroelectrometallurgical technology for processing bismuth dross and oxides (the intermediate products of lead bullion refining by the Betterton-Kroll process) to obtain crude bismuth. The research focuses on bismuth dross (3–5% Bi; 80–85% Pb) remelted at 500–600°С in the presence of NaNO3 and NaOH, as well as the obtained alkaline melt (bismuth oxides, 1–5% Bi; 60–70% Pb). The conducted experiments allowed us to determine optimal parameters of the main steps of processing bismuth oxide, as well as the characteristics of obtained products. Reduction smelting of bismuth oxides at 1150°C (with the addition of sodium carbonate, quartz and fine coke in the amount of 66, 25 and 5% of bismuth oxides mass, respectively) is proposed, leading to bismuth lead formation. Its decoppering is carried out at 350–600°C with 2.0% sulfur (by its weight), added to the melt. We propose to carry out the alkaline treatment of the decoppered Pb-Bi alloy at 500oC in contact with sodium hydroxide, sodium nitrate and sodium chloride, taken in amounts up to 10.2, 8.3 and 1.4% by weight of bismuth lead, respectively. Subsequent electrolysis comprises electrolytic processing of purified Pb-Bi alloy ingots at 550oC. The electrolyte consists of a melt with the following composition, %: NaCl – 7, KCl – 35, PbCl2 – 18 and ZnCl2 – 40. As a result, two end products were obtained by the proposed bismuth oxide processing. The anodic product at the second stage of electrolysis, crude bismuth (yielded 1.1% by the weight of oxides) contains 93.62% Bi and 4.14% Pb, extraction from oxides amounts to 19.0% Bi and 0.1% Pb. About 1.2% Bi and 9.1% Pb of their initial content in the oxides are transferred to the cathodic product containing 0.033% Bi and 97.83% Pb (the yield equalled 5.1% of the oxides).

Abstract:

Reversible solid oxide cells (SOCs) have drawn much attention as alternative energy conversion and storage devices owing to their high efficiency and environmental benignity. However, considering their high operating temperature involves unwanted chemical reactions, thermal stress, and high system costs it is essential to lower their operating temperature for commercial feasibility. At reduced temperature, on the other hand, the catalytic activity of oxygen reduction reactions (ORRs), oxygen evolution reactions (OERs), and oxygen ionic transport are diminished due to their thermally activated nature. For example, the most widely used yttria-stabilized zirconia (YSZ) shows significantly decreased ionic conductivity at reduced temperature (e.g. 0.003 S/cm at 600 °C), which is not sufficient for high performing SOCs. Among various alternative oxygen ionic conducting materials, rare-earth stabilized bismuth oxides have been well known as super ionic conductors which exhibit 30 times higher conductivity than that of YSZ. However, the ionic conductivity of stabilized bismuth oxides is significantly decreased due to their phase transformation from cubic phase to rhombohedral phase at 600 °C. In this regard, it is crucial to carefully utilize proper doping material for enhancing their stability while retaining their high ionic conductivity. In this study, we newly developed stabilized bismuth oxide with superior ionic conductivity and durability at 600 °C via triple-doping strategy. Initial ionic conductivity of the stabilized bismuth oxide was maintained for more than 1000 hours at 600 °C with no phase transformation. This stabilized bismuth oxide was combined with conventional La0.8Sr0.2MnO3- δ (LSM) as a novel oxygen electrode. Furthermore, a SOC with this novel air electrode showed high electrochemical performance both in the fuel cell (FC) and the electrolysis (EC) modes (e.g. 2.5 W/cm2 and 1.4 A/cm2 at 1.3V at 700 °C in the FC and the EC modes, respectively).

Abstract:

Polymer nanocomposites have recently been introduced as lead-free shielding materials for use in medical and industrial applications. In this work, novel shielding materials were developed using low-density polyethylene (LDPE) mixed with four different filler materials. These four materials are cement, cement with iron oxide, cement with aluminum oxide, and cement with bismuth oxide. Different weight percentages were used including 5%, 15%, and 50% of the cement filler with LDPE. Furthermore, different weight percentages of different combinations of the filler materials were used including 2.5%, 7.5%, and 25% (i.e., cement and iron oxide, cement and aluminum oxide, cement and bismuth oxide) with LDPE. Bismuth oxide was a nanocomposite, and the remaining oxides were micro-composites. Characterization included structural properties, physical features, mechanical and thermal properties, and radiation shielding efficiency for the prepared composites. The results show that a clear improvement in the shielding efficiency was observed when the filler materials were added to the LDPE. The best result out of all these composites was obtained for the composites of bismuth oxide (25 wt.%) cement (25 wt.%) and LDPE (50 wt.%) which have the lowest measured mean free path (MFP) compared with pure LDPE. The comparison shows that the average MFP obtained from the experiments for all the eight energies used in this work was six times lower than the one for pure LDPE, reaching up to twelve times lower for 60 keV energy. The best result among all developed composites was observed for the ones with bismuth oxide at the highest weight percent 25%, which can block up to 78% of an X-ray.

Abstract:

This thesis describes the growth of bismuth oxide (Bi2O3) and multiferroic bismuth ferrite (BiFeO3) films via chemical vapour deposition (CVD). The synthesis of a range of bismuth(III) β-diketonate complexes was carried out via a ligand-exchange reaction between [Bi(N(SiMe3)2)3] and the respective free ligand, and crystal structures of [Bi(dbm)3]2 and [Bi(acac)3] are reported. The decomposition of these complexes was studied via DSC-TGA to assess their potential as single-source precursors to Bi2O3, and the mass transport characteristics of the volatile complexes [Bi(mmp)3], [Bi(thd)3] and [Bi(OtBu)3] were studied. Bi2O3 films were grown via the LPCVD reaction of the single-source precursor [Bi(OtBu)3]; the crystalline phase (and band-gap) of the resultant films depended strongly upon the reactor conditions. Films were tested for photo-oxidation of water under UV-light, revealing high activities comparable to those of TiO2 films described previously. [Bi(dbm)3]2 was utilised as a single-source precursor to β-Bi2O3 films via AACVD, together with the growth of Pt(0) films using H2PtCl6.6H2O as a precursor. Pt-nanoparticle Bi2O3 films were grown via a ‘one-pot’ AACVD reaction of both precursors; composite Pt-Bi2O3 films were able to evolve hydrogen via the photo-reduction of water, a property not observed for films containing either Pt or Bi2O3 alone. BiFeO3 films were grown via a multi-source LPCVD reaction between [Fe(acac)3], [Bi(OtBu)3] and air, as well as via the dual-source reaction of [Bi(OtBu)3] and [Fe(OtBu)3]2 without oxidising gas, and, furthermore, via the single-source precursor [{Cp(CO)2Fe}BiCl2] using AACVD. Magnetometry revealed low temperature ferromagnetism and spin-glass behaviour, characteristic of larger particle sizes. Ferroelectric measurements revealed low polarisation but nevertheless indicated films were multiferroic at room temperature. A selection of these films were tested for photo-oxidation of water under visible-light; films displayed high photoactivities with rates in excess of those from optimised TiO2 films measured under UV-light, highlighting the potential of BiFeO3 films as strong visible-light active photocatalysts.

Optical measurements were taken in the range of 0.4 - 11 pm at 300 K and 77 K using a spectrometer. The results show that near the band edge, there is evidence of indirect transitions at 2.3 eV and excition transitions at 1.8 eV. Low temperature measurements revealed peaks of free carrier absorption in the visible light range at 1.7 eV and 2.1 eV. Illuminated samples at low temperature revealed empty donor levels in the visible range at 1.6-1.9 eV and 2.1 eV, indicating the presence of the photochromic effect and photorefractivity.<br>by Grace W.

Abstract:

Cyclic voltammetry experiments were performed to compare the electrodeposition characteristics of bismuth on ruthenium. Two types of electrodes were used for comparison: a Ru shot electrode (polycrystalline) and a thin film of radio-frequency sputtered Ru on a Ti/Si(100) support. Experiments were performed in 1mM Bi(NO3)3/0.5M H2SO4 with switching potentials between -0.25 and 0.55V (vs. KCl sat. Ag/AgCl) and a 20mV/s scan rate. Grazing incidence x-ray diffraction (GIXRD) determined the freshly prepared thin film electrode was hexagonally close-packed. After thermally oxidizing at 600°C for 20 minutes, the thin film adopts the tetragonal structure consistent with RuO2. a hydrated oxide film (RuOx?(H2O)y) was made by holding 1.3V on the surface of the film in H2SO4 for 60 seconds and was determined to be amorphous. Underpotential deposition of Bi was observed on the metallic surfaces and the electrochemically oxidized surface; it was not observed on the thermal oxide.

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2007.<br>Includes bibliographical references (leaves 39-43).<br>The hole-doped cuprate Bi ... is doped with lead to the solubility limit of x = 0.38 and studied using STM/STS in the overdoped regime where Tc < 2K. Despite the high lead content, residual supermodulations are observed in the BiO plane. In agreement with previous studies on (Pb,Bi)-2201, there is no separation of the sample into Pb-rich and Pb-poor domains, nor is there a spectral correlation with Pb location. Differential tunneling conductance is modeled using the van Hove scenario, wherein modulated regions are shown to have higher values of EVHS than flat regions.

Abstract:

Samples from both hydrothermal and melt growth techniques were characterized for absorption, index of refraction, and photorefractive dynamics. Doped hydrothermal samples possessed similar photorefractive properties to nominally undoped melt growth samples. BSO operates over a wide range of wavelengths, and it would be desirable to maintain the sensitivity of BSO while controlling the absorption coefficient at wavelengths into the infrared laser-diode operating region. The doped hydrothermal crystal is very transparent, having a light green color. In addition, a variety of response times may be useful in implementing optical analog devices in analogue to electronic devices. For example, heavy doping with chrome produces a dark, almost black, sample with an extremely long response time.

Abstract:

Bismuth silicon oxide is a high-index (2.54 at 514 nm) electrooptic and photorefractive material used for optical information processing devices such as the Pockels readout optical modulator (PROM), the photorefractive incoherent-to-coherent optical converter (PICOC), and volume holographic optical elements (VHOEs). In the latter two applications, the bismuth silicon oxide crystals have typically been used uncoated, even though the resultant high single-surface reflectivity (~19%) gives rise to problematic multiple reflections. For example, in the use of two-beam coupling experiments in Bi12SiO20 for signal amplification1 or materials parameter analysis, the modulation depth of the volume holographic gratings is reduced by multiple reflections, and the effective gain is decreased.2 For such experiments, a two-layer quarterwave stack of electron-beam deposited zirconium dioxide and magnesium fluoride was employed to fabricate a broadband (500–800-nm) AR coating, which encompassed both the write (514-nm) and read (633-nm) beams. At both wavelengths, the reflectivity was reduced to ~1 %, and the coating was found to be relatively insensitive to large angles of incidence (of the order of 45°). In two-beam coupling experiments, the effective gain was increased by 10%, and the resolution of the technique was significantly improved for low-intensity measurements.
