摘要: 半导体光催化剂因其高效、生态友好、成本低等优点,可用于解决能源与环境问题。层状双金属氢氧化物(LDHs)是一类由两种或两种以上金属阳离子组成的金属氢氧化物,结构由主体层板和层间的插层阴离子及水分子相互交叠构成。LDHs纳米材料具有带隙可调、比表面积大、种类多样、成本低廉并且易与其他材料复合实现功能化等优点,因此LDHs纳米材料在光催化领域中表现出良好的应用前景。本文系统综述了近年来LDHs纳米材料的制备方法及其在光催化分解水制氢、吸附和降解有机染料,以及光催化还原二氧化碳等光催化领域的最新研究进展,为未来高性能LDHs基纳米催化材料的制备及催化性能调控提供了一定的参考。

Abstract: Semiconductor photocatalysts can be used to solve energy and environmental problems due to their high efficiency, ecological friendliness and low cost. Layered double hydroxides (LDHs) are a class of metal hydroxides composed of two or more metal cations, with main laminates and interlayer anions and water molecules overlapping each other. LDHs nanomaterials have the advantages of adjustable band gap, large specific surface area, various types, low cost and easy to composite with other materials to realize functionalization, therefore LDHs nanomaterials show good application prospects in the field of photocatalysis. This article systematically reviewed the recent developments in the preparation of photocatalytic LDHs nanomaterials and their photocatalytic application of the decomposition water to produce hydrogen, the adsorption and degradation of organic dyes, and the photocatalytic reduction of carbon dioxide. It provides a certain reference for the preparation and regulation of catalytic performance of high-performance LDHs based nano-catalytic materials in the future.

Key words: layered double hydroxide (LDHs), nanomaterial, photocatalysis, catalyst, adsorption, degradation
