摘要
多酸作为一种无机电活性物质,可经历可逆的多电子氧化还原过程,使其在化学修饰电极和电催化研究领域有很大的吸引力~([1])。此外,多酸是优秀的无机构筑块,与有机配体结合,能形成具有新型功能特性的有机-无机杂化多金属氧酸盐,兼具有机与无机基块的性能。离子液体具有导电率高、蒸汽压小、稳定性好等特点,在电化学领域的应用不断拓展~([2])。本文将多酸和离子液体的优良电化学性能以及纳米材料的特性三者有机地结合起来,采用低热固相化学反应制备系列新型有机-无机杂化离子液体-多金属氧酸盐纳米材料,并将其构筑成化学修饰碳糊电极,研究其电催化性能。研究结果表明,合成的离子液体-多金属氧酸盐纳米材料对亚硝酸盐、溴酸盐、过氧化氢等均具有良好的电催化性能。
Polyoxometalates(POM) are a kind of inorganic electroactive materials, their abilities to undergo reversible multi-electron redox processes endow them with very attraction in chemically modified electrode and electrocatalytic research. POM anions have been also found to be versatile inorganic building blocks. The combination of the inorganic building blocks with organic molecules has been shown to lead to a variety of organic-inorganic hybrid materials, which have the advantages of both organic and inorganic building blocks. Ionic liquids(ILs) present potential application prospects in electrochemistry owing to their high conductivities, low vapour pressures and good stabilities. We combine the versatile electrochemical properties of ILs and POMs as well as the advantages of nanomaterials to facile synthesize novel organic-inorganic IL-POM nanomaterials by low-heating solid-state chemical reaction. As-prepared IL-POM nanomaterials were fabricated bulk-modified carbon paste electrodes(CPEs) to investigate their electrocatalytic activities. The results reveal that they possess excellent electrocatalytic activities toward the reduction of nitrite, bromate and hydrogen peroxide.
