摘要

摘要: 光催化技术作为一种新兴的高效可持续技术,在环境领域具有广泛的应用前景。然而,多数光催化材料在失去外界光源的能量供应后,短时间内不再产生电子空穴对,从而迅速丧失催化反应活性。但光催化记忆材料具有独特的催化记忆效应,即在黑暗条件下仍可表现出一定的催化活性,进而克服了以上难题。主要概述了光催化记忆材料的基本工作原理,将现有的光催化记忆材料归类,并总结了光催化记忆材料在环境领域的主要应用方向,包括新能源的生产、难降解有机污染物的氧化去除、重金属污染物的还原去除及病原微生物的灭活,最后展望了光催化记忆材料的发展前景。

Abstract: Photocatalytic technology, as an emergingly efficient and sustainable technology, has broad application prospect in the environmental field. However, most photocatalytic materials will not generate electron-hole pairs in a short period of time without the energy supply of the external light source, and thus rapidly lose the catalytic activity. Photocatalytic memory materials have a unique ability, named as catalytic memory effect, to maintain catalytic performance under dark environments for overcoming the above challenges. This review article mainly outlined the basic principles of photocatalytic memory materials, classified the existing photocatalytic memory materials, summarized the application of photocatalytic memory materials in the environmental field, including the production of energy sources and the oxidation of refractory organics, the reduction of heavy metal and the inactivation of pathogenic microorganisms, and prospected for the future development of photocatalytic memory materials.
