摘要
近年来,有关类水滑石拓扑转变材料在光、电催化领域如产氢、C1化学转化等方面的研究被广泛报道。研究表明,在不同的煅烧温度、气氛等拓扑转变条件下处理类水滑石,不仅可以提高活性位的分散程度,而且可以实现催化剂物相组成、特定晶面和界面结构的调控。该材料在多种能源催化转化利用中呈现出优越的性能。本文介绍了类水滑石拓扑转变的过程及机制,并分别从光催化、电催化2个方面综述类水滑石拓扑转变材料在能源催化领域的研究进展。
In recent years,research concerning layered double hydroxides(LDHs)topological transformation materials in the field of photocatalysis and electrocatalysis,such as hydrogen production,and chemical transformation of C1 species,has been widely reported.Research shows that not only the dispersion of active site can be improved,but also phase composition,specific crystal plane and interface structure can be regulated by selecting different calcination temperature,atmosphere and other topological transformation conditions.This kind of materials thus exhibits superior performance in catalytic conversion and utilization of various energy sources.In this review,we will introduce the process and mechanism of LDHs topological transformation,and then review the research progress of LDHs topological transformation materials in energy catalysis from the aspects of photocatalysis and electrocatalysis.
