Abstract
Photocatalytic carbon dioxide (CO2) reduction has gained vast attention as one of the effective approaches to alleviate energy crisis and greenhouse effect. Two-dimensional layered bimetallic hydroxides (LDHs) show great potential in photocatalytic reduction of CO2 owing to their special layered structure, variability of component metal elements, and interlayer anion exchangeability. In this review, the research progress of CO2 reduction using LDHs-based photocatalysts was first described by co-occurrence and cluster analysis of research hotspots and trends. Then, photocatalytic activity toward CO2 reduction of various reported LDHs and modified LDHs-based photocatalysts using different kinds of strategies like elemental doping, defect engineering, heterogeneous structure design, morphology regulation, and surface plasmonic resonance (SPR) effect was thoroughly discussed. Moreover, photocatalytic mechanism insights of LDHs-based photocatalytic materials for CO2 reduction were summarized. Last but not least, the challenge and research perspective in this field were proposed. This review aims to provide comprehensive insights and guidance for further research and practical application of LDHs-based photocatalysts for conversion of CO2 into value-added products.
光催化还原二氧化碳(CO2)作为缓解能源危机和温室效应的有效方法之一,已受到广泛关注。二维层状双金属氢氧化物(LDHs)因其特殊的层状结构、组成金属元素的可变性和层间阴离子交换性,在光催化还原二氧化碳方面显示出巨大的潜力。在本综述中,首先通过对研究热点和趋势的共现和聚类分析,阐述了利用基于 LDHs 的光催化剂还原 CO2 的研究进展。然后,深入探讨了已报道的各种 LDHs 以及利用元素掺杂、缺陷工程、异质结构设计、形态调控和表面等离子体共振(SPR)效应等不同策略修饰的 LDHs 基光催化剂还原 CO2 的光催化活性。此外,还总结了基于 LDHs 的光催化材料用于还原 CO2 的光催化机理。最后还提出了该领域的挑战和研究前景。本综述旨在为进一步研究和实际应用基于 LDHs 的光催化剂将 CO2 转化为高附加值产品提供全面的见解和指导。 图文摘要
