羟基氧化物微结构因具有特殊结构、高比表面积和高活性的性质,显示出卓越的分子识别特性、表面反应活性和电催化活性。近年。运用功能单元作为负载提高羟基氧化物微结构的催化性能成为研究者关注的热点。本文将羟基氧化物的结构优势与功能单元的催化特性结合起来,综述了负载型羟基氧化物。如FeOOH和AIOOH的合成方法及应用,分析了负载了功能单元(贵金属、金属氧化物、羟基氧化物等)的羟基氧化物在循环伏安法、交流阻抗、计时电流法等电化学催化研究方面的进展。并对负载型羟基氧化物的研究方向进行展望。
With its special structure, the high surface area and the high active nature, the oxyhydroxide microstructure enjoys high molecular recognition performance,good surface reactivity and electrochemistry properties. The functional unit of the oxyhydroxide microstructure is more and more applied in electrochemistry studies. On the basis of the functional unit's catalytic activity and the oxyhydroxidels structure superiority, this paper reviews the synthesis and applications of supported oxyhydroxide, such as AIOOH and FeOOH, and the application of noble metal, metal oxides, hydroxy oxide and double-layer-like hydroxyl oxide as functional units on oxyhydroxide modified electrodes in electrochemistry, and their prospective development.
