Full textA study on carbon paste electrode (CPE) materials containing 1-methyl-3-octylimidazolium bis (trifluoromethylsulfonyl) imide [MOIM[Tƒ2N] – a hydrophobic room temperature ionic liquid (IL) - is reported. CPEs with (a) the IL as the only binder (ILCPE) and (b) 1:1 (v/v) IL: paraffin mixture as the binder (ILPCPE) were prepared, characterized, and applied to the electrodeposition of films of multivalent transition metal oxides (MV-TMO) from five precursor ions (Fe2+, Mn2+, Cu2+, Co2+, Ce4+) in aq. KCl. Cyclic voltammetry (CV) showed a potential window of +1.5 V to -1.8 V regardless of the electrode type, including the traditional paraffin CP electrode (PCPE). However, the IL increased the background current by 100-folds relative to paraffin. The electrochemical impedance spectroscopy (EIS) of ILPCPE in aq. KCl (0.1M) revealed two phase angle maxima in contrast with the single maxima for PCPE and ILCP. The study also included the CV and EIS investigation of the electrode kinetics of the Fe(CN)6 3-/4 redox system at these electrodes. The electrodeposition of Fe2+, Co2+, and Mn2+ possibly in the form of the MV-TMOs FexOy, CoxOy, and MnxOy, respectively, onto the electrodes was confirmed by the observation of new and stable cathodic and anodic peaks in a fresh precursor ion –free medium. CVs of H2O2 as a redox probe supported the same conclusions. Both ATR-FTIR spectra and SEM image of surface samples confirmed the formation of electrodeposited films. This study demonstrated that the use of this hydrophobic IL alone or in combination with paraffin as a binder gives viable alternative CPE materials with better performance for the electrodeposition of MV-TMOs films than the paraffin CPE. Thus, in combination with the easy preparation methods and physical “morpheability” in to any shape, these CPEs are potentially more useful in electrochemical technologies based on high surface-area MV-TMO films in general, and MnxOy films in particular.

Nanostructured electrode materials for electrochemical energy storage systems have been shown to improve both rate performance and capacity retention, while allowing considerably longer cycling lifetime. The nano-architectures provide enhanced kinetics by means of larger surface area, higher porosity, better material interconnectivity, shorter diffusion lengths, and overall mechanical stability. Meanwhile, active materials that once were excluded from use due to bulk property issues are now being examined in new nanoarchitecture. Silicon was such a material, desired for its large lithium-ion storage capacity of 4,200 mAh g[superscript]-1 and low redox potential of 0.4 V vs. Li/Li[superscript]+; however, a ~300% volume expansion and increased resistivity upon lithiation limited its broader applications. In the first study, the silicon-coated vertically aligned carbon nanofiber (VACNF) array presents a unique core-shell nanowire (NW) architecture that demonstrates both good capacity and high rate performance. In follow-up, the Si-VACNFs NW electrode demonstrates enhanced power rate capabilities as it shows excellent storage capacity at high rates, attributed to the unique nanoneedle structure that high vacuum sputtering produces on the three-dimensional array. Following silicon’s success, titanium dioxide has been explored as an alternative highrate electrode material by utilizing the dual storage mechanisms of Li+ insertion and pseudocapacitance. The TiO[subscript]2-coated VACNFs shows improved electrochemical activity that delivers near theoretical capacity at larger currents due to shorter Li[superscript]+ diffusion lengths and highly effective electron transport. A unique cell is formed with the Si-coated and TiO[subscript]2-coated electrodes place counter to one another, creating the hybrid of lithium ion battery-pseudocapacitor that demonstrated both high power and high energy densities. The hybrid cell operates like a battery at lower current rates, achieving larger discharge capacity, while retaining one-third of that capacity as the current is raised by 100-fold. This showcases the VACNF arrays as a solid platform capable of assisting lithium active compounds to achieve high capacity at very high rates, comparable to modern supercapacitors. Lastly, manganese oxide is explored to demonstrate the high power rate performance that the VACNF array can provide by creating a supercapacitor that is highly effective in cycling at various high current rates, maintaining high-capacity and good cycling performance for thousands of cycles.

In this work, three dimensional graphene was synthesized by the chemical vapor deposition method using nickel foam as a template. Activated carbon was dip-coated with graphene to combine carbon materials of different dimensions. Subsequently, MnO2/activated carbon/graphene composite electrodes with hierarchical pore structure and controllable MnO2 loading were synthesized using a self-limiting growth method; this was achieved by redox reactions of KMnO4 on sacrificial carbon materials. Furthermore, the capacitances between the carbon-only electrodes and the MnO2/carbon composite electrodes were compared. The former one are normally electrochemical double-layer capacitors, nevertheless, the latter one also show pseudocapacitive properties. The optimum MnO2/activated carbon/graphene composite electrode exhibited a specific capacitance of 813.0 F/g at a current density of 1 A/g, as well as good stability of 98.4% capacitance retention after 1000 cycles. When the symmetric solid-state supercapacitor was built from MnO2/activated carbon/graphene composite electrodes, it showed an energy density of 33.9 Wh/kg and a power density of 319.3 W/kg. Results of the feasibility tests indicate that the composite electrodes can be promising for supercapacitor applications.

Cr(VI) is one of the pollutants of major concern in the environment due to its high toxicity and carcinogenicity. In oxic soils, organic matter (OM) and black carbon (BC) are the predominant reductants that can reduce toxic Cr(VI) to less toxic Cr(III). However, Cr(VI) still can be leached to deeper layers of soil or even into groundwater. The low reduction rate of Cr(VI) is presumably attributed to the reactions of other soil constituents with Cr(VI) that inhibit the reduction of Cr(VI) by OM and BC. Thus, in this study, the influences of hydrous oxides of Fe and Mn on the Cr(VI) reduction of BC were investigated. The results showed that the co-existence of goethite with BC inhibited the Cr(VI) reaction of BC due to the fast adsorption rate and strong desorption hysteresis of Cr(VI) on goethite. Nonetheless, the prolonged reaction of Cr(VI) with BC and goethite removed Cr(VI) from solution through the adsorption of Cr(VI) and the subsequent reduction of adsorbed Cr(VI) to Cr(III). The resulting Cr(III) is either released back into solution or bound on BC. When MnO2 coexisted with BC, the aqueous Cr(III) were oxidized to Cr(VI) by MnO2. The Cr(III) oxidation and releasing back into solution occur as coupled reactions. The oxidation of aqueous Cr(III) by MnO2 inhibited the Cr(VI) reduction by BC when MnO2 coexisted with BC. At lower pH, the net positive charge on the surface of BC resulted in electrostatic repulsion between Cr(III) and BC. On the other hand, the oxidation of Cr(III) by Mn oxide led to the formation of Cr(VI) in solution, which was subsequently reduced by BC and consequently enhanced the removal of total Cr by BC at lower pH when BC coexisted with MnO2. In summary, the presence of Fe and Mn oxides inhibited the reduction of Cr(VI) by BC, leading to an increasing risk of Cr(VI) contamination in soil. Thus, the interactions between different soil consitutents need to be considered in order to have better understanding of the environmental risks of Cr contamination in soil.

Characteristics of electrochemical capacitors include higher energy density, higher power density, and longer life cycle. They can be applied in 3C (Computer, Communication, Consumptive electronic product) and the quality, reliability and cost competition advantage of 3C products can be improved. Thus, Ti will be sputtered on Si and then Co will be sputtered on Ti by radio frequency (RF) and directly subsequent CVD with different different NH3 flow rates as well as temperatures will be used to prepared carbon nanotubes. Next, carbon nanotubes will be annealed by nitrogen-plasma treatment. Finally, manganese-cobalt-zinc oxide will be sputtered on inner and outer walls of carbon nanotubes by radio frequency (RF). In addition, the electrodes will be tested by SEM, XPS, gas adsorption meter, and Raman, etc... Furthermore, in order to find better prepared methods and conditions of the electrodes, the cyclic voltammetry (CV) will be taken for the electrodes.

A study was conducted to use the Chromium Hexacyanoferrate(II) [KCrHCF(II)] to modify the carbon paste electrode (CPE). The responding current for detecting H2O2 or glucose at the reductive potential was measured to determine the concentrations H2O2 or glucose. The results showed that the carbon paste electrode modified by KCrHCF(II) possessed a good linearity for detection of H2O2 (the linear range was 0.0125 ~ 15 mM, R2 = 0.9997) and that the sensitivity for reduction of H2O2 was about 151.55 μA/cm2-mM H2O2. The sensitivity (2.01 mA/cm2-mM H2O2) for reduction of H2O2 for the CPE modified by the nanosized KCrHCF(II) could be elevated to about 13 times of that of CPE modified by the unnanosized KCrHCF(II). The linear range was 0.005 ~ 17 mM and the R2 was 0.9995 for reduction of H2O2 for the CPE modified by the nanosized KCrHCF(II). The results showed that the KCrHCF(II) could increase the ability of reduction of H2O2 and if the KCrHCF(II) was nanosized, it could increase the ability of reduction of H2O2 significantly and consequently increase the responding current. If the mixed method was used to immobilize the Glucose Oxidase onto the CPE modified by the KCrHCF(II), the linear range for the detection of glucose was about 0.05 ~ 1.95 mM (R2 = 0.9965) and the sensitivity was about 1.28 μA/cm2-mM C6H12O6. If the entrapping method was used to immobilize the Glucose Oxidase, the linear range for the detection of glucose could be elevated to about 0.025 ~ 1.625 mM (R2 = 0.9993), and also the sensitivity could be elevated to about 23.11 μA/cm2-mM C6H12O6. Furthermore, we had accomplished in the preparation of the amperometric sensing strips for the detection of glucose by using the entrapping method and the screen-printing technique. Through the detection of glucose by the screen-printed electrodes (SPEs), the sensitivity was about 24.76 μA/cm2-mM C6H12O6 and the linear range was about 0.025 ~ 1.875 mM (R2 = 0.9968). The results were not quite satisfactory but since the KCrHCF(II) possesses the pretty good characteristic of catalytic ability for reduction of H2O2. If the method of immobilization of enzyme can be further modified, the sensitivity and linear range for detection of glucose will be elevated and this will be the goal of our further study.
