Abstract:
In this work, octahedral shaped PbTiO3-TiO2 nanocomposites have been synthesized by a facile hydrothermal method, where perovskite ferroelectric PbTiO3 nanooctahedra were employed as substrate. The microstructures of the composites were investigated systemically by using XRD, SEM, TEM and UV-Vis spectroscopy. It was revealed that anantase TiO2 nanocrystals with a size of about 5 nm are dispersed on the surface of the {111} facets of the nanooctahedron crystals. Photocatalytic hydrogen production of the nanocomposites has been evaluated in a methanol alcohol-water solution under UV light enhanced irradiation. The H2 evolution rate of the nanocomposites increased with an increased loading of TiO2 on the nanooctahedra. The highest H2 evolution rate was 630.51 μmol/h with the highest concentration of TiO2 prepared with 2 mL tetrabutyl titanate, which was about 36 times higher than that of the octahedron substrate. The enhanced photocatalytic reactivity of the nanocomposites is possibly ascribed to the UV light absorption of the nanooctahedral substrates, efficient separation of photo-generated carriers via the interface and the reaction on the surface of the TiO2 nanocrystals.

Abstract:
Pd is one of the most promising catalysts for carbon dioxide electroreduction (CO2RR) to formate (HCOO-). However, the lack of understanding of the active phase remains remains obscure with the role of different crystal facets in the formation of formic acid. Herein, Pd nanocubes and nanooctahedra particles with Pd (100) and (111) facets were, respectively, prepared. Compared with ordinary Pd nanoparticles and Pd octahedra, Pd nanocubes exhibited the most excellent electrocatalytic performance of carbon dioxide reduction, achieving a Faraday efficiency of 96% for formate production at a low applied potential of-0.20 V (vs RHE) in 0.5 M KHCO3. At the same time, first-principles theoretical calculations also showed that the Pd (100) surface is more conducive to the conversion of CO2 to HCOO* intermediates, thereby promoting the formation of formic acid. This result indicates that the Pd (100) crystal plane is more conducive to the reduction of CO2 to formate. This research has important guiding significance for exploring the efficient reduction of carbon dioxide to formic acid catalyst.

Full text
Abstract:
Stoichiometric antimony selenide (Sb2Se3) nanocrystals have been successfully engineered by a facile physical vapor deposition method, employing a single precursor of polycrystalline Sb2Se3 charge in a closed quartz ampoule under high vacuum without any foreign seed or extraneous chemical elements. This work underscores the efficacy of the vapor deposition process and provides synthetic strategies to scale down bulk Sb2Se3 into novel nanostructures. The morphological evolution of the tailored architecture was examined on micro and nano size scales by scanning electron microscopy and high-resolution transmission electron microscopy. The intrinsic mechanism governing the nanostructure formation is revealed as layer-by-layer growth, related to the unique layered structure of Sb2Se3. The optical properties of the grown crystals were probed by UV–vis–NIR and photoluminescence tools. The band-gap values of the microfibers, nanorods, nanooctahedra and nanospheres estimated from UV–vis–NIR analysis are found to be 1.25, 1.47, 1.51 and 1.75 eV, respectively. Powder X-ray diffraction, energy-dispersive analysis by X-rays, X-ray photoelectron spectroscopy, Raman spectroscopy and photoluminescence studies confirmed the quality, phase purity and homogeneity of the as-grown nanostructures. The adopted physical vapor deposition method is thus shown to be a simple and elegant route which resulted in the enhancement of the band gap for the Sb2Se3 samples compared with their counterparts grown by chemical methods. This approach has great potential for further applications in optoelectronics.

Abstract:
Pyrochlore-type potassium tantalate (K2Ta2O6 ) was successfully synthesized through a facile hydrothermal method. X-Ray diffraction and electron microscopy reveal that pure K2Ta2O6 consisting of a nanooctahedral structure could be obtained at 180°C for 24 h. The photocatalytic activities of K2Ta2O6 were examined using aqueous solutions under ultraviolet irradiation. The degradation result of the Rhodamine B dye indicated that the pyrochlore-type potassium tantalates exhibited a remarkably higher photocatalytic activity than the perovskite phase sample. This high photocatalytic activity is ascribed to both the high position of the conduction band and the high separation efficiency of electron-hole pairs of the pyrochlore structure.

Potassium tantalates is one kind of important semiconductor with potential applications on photoelectric transformation and photocatalysis. Herein, Au nanoparticles were grown on the surface of two kinds of potassium tantalates, KTaO3 nanocubes and K2Ta2O6 nanooctahedron, by flexible reducing HAuCl4, and KTaO3/Au and K2Ta2O6/Au hetero-nanostructures were formed. Although the Au nanoparticles loading enhances the light absorption, KTaO3/Au and K2Ta2O6/Au hetero-nanostructures exhibit different photoelectric properties. The difference of photoelectric properties of two kinds of potassium tantalates/Au hetero-structures hint the photoelectric-property enhancement depends on multiple factors.

Abstract:
The monodisperse Mn2O3 nanooctahedron, Mn3O4 nanorices, NiO nanoflowers and Cu2O nanoroses have been synthesized via a facile solvothermal approach in the presence of poly (vinyl-pyrrolidone)/stearic acid (PVP/SA) as capping agent. Field-emission scanning electron microscopes (FESEM) and X-ray powder diffraction (XRD) were employed to detect the prepared products. Furthermore, the synthetic method appears to be a general approach and other metal oxide materials with various well-defined nano/microstructures can be fabricated by the similar method. The as-obtained metal oxides nanostructures were used as catalyst in CO oxidation, and the octahedral Mn2O3 nanoparticles exhibited relatively high activity. Complete conversion CO to CO2 can be achieved at a temperature as low as 240 °C over Mn2O3 catalyst, which was about 70 and 100 °C lower than that of Mn3O4 and NiO, respectively.

Abstract:
Decorating Cu2O nanooctahedra with small Au nanograins is a superior strategy to utilize photogenerated charge carriers without generating hot electrons. Photocatalytic activity in these heteronanoparticles is improved even upon low-power excitation.

Abstract:
Abstract The thermal stability of Au nanoparticles on ceria support of various morphology (nanocubes, nanooctahedra, and {111}-nanofacetted nanocubes) in oxidizing and reducing atmospheres was investigated by electron microscopy. A beneficial effect of the reconstruction of edges of ceria nanocubes into zigzagged {111}-nanofacetted structures on the inhibition of sintering of Au nanoparticles was shown. The influence of different morphology of Au particles on various ceria supports on the reducibility and catalytic activity in CO oxidation, and CO PROX of Au/ceria catalysts was also investigated and discussed. It was shown, that ceria nanocubes with flat {110} terminated edges are more suitable as a support for Au nanoparticles, used to catalyze CO oxidation, than zigzagged {111}- nanofacetted structures.
