Photoreduction of CO into solar fuels is usually regarded as one of the promising solutions to overcome environmental pollution and the energy crisis. The main challenge in CO photoreduction (CO PR) is the low efficiency and poor selectivity. Layered double hydroxides (LDHs) are a class of 2D materials, consisting with M(OH) octahedra in the host layers and intercalated anions. Owing to the tuneable composition, particle size, morphology, and virtue coordinatively unsaturated active sites, a series of efficient strategies (morphology control, heterostructure, defect control, etc.) in LDH-based photocatalysts have been efficiently developed to enhance the photocatalytic selectivity and activity for CO PR. This review summarizes recent progress on the LDH-based photocatalysts for CO PR.
将CO光还原为太阳能燃料通常被认为是克服环境污染和能源危机的一种有前景的解决方案。CO光还原（CO PR）的主要挑战是效率低和选择性差。层状双氢氧化物（LDHs）是一类二维材料，主体层由M(OH)八面体和层间插层阴离子组成。由于其组成、粒径、形态可调，以及具有配位不饱和活性位点的优点，基于LDH的光催化剂中已经有效地开发了一系列有效策略（形态控制、异质结构、缺陷控制等）来提高CO PR的光催化选择性和活性。本文综述了基于LDH的CO PR光催化剂的最新进展。
