摘要:

我国提出2030年“碳达峰”和2060年“碳中和”战略目标. 将CO2转化为高附加值的化学产品和液态燃料, 在实现碳减排的同时, 还可减轻对煤、 石油等传统资源的依赖, 具有重要意义. 光催化CO2还原是一种非常重要的途径, 设计和制备高效的CO2还原光催化剂是关键. 通过半导体和金属或具有匹配的电子带结构的半导体之间形成良好的异质结结构可以有效地促进电荷转移并抑制光生电子和空穴的重新复合, 从而提高光催化性能. 本综合评述重点讨论了氧化物异质结构用于光催化CO2还原的最新进展, 系统总结了形成异质结构的类型、 组成等因素, 对提高CO2光催化性能的内在机理进行了深入阐述, 并对该领域研究发展的方向进行了展望.

Abstract:

China has put forward the strategic goals of “carbon emissions peak” in 2030 and “carbon neutrality” in 2060. It is of great significance to convert CO2 into high-value-added chemical products and liquid fuels, which can reduce the dependence on coal, oil and other traditional resources while achieving carbon emission reduction. Photocatalytic CO2 reduction is a very important way, and the design and preparation of efficient photocatalysts for CO2 reduction are the key. Well-defined heterojunction structures between metals and semiconductors or semi- conductors with matching electronic band structures can effectively promote charge transfer and inhibit the recombination of photogenerated electrons and holes, thus improving the photocatalytic performance. This review focuses on the recent progress of oxide-based heterostructures for photocatalytic CO2 reduction, and systematically summarizes the types and components of the formation of heterostructures, and expounds the internal mechanism of improving the performance of CO2 photocatalysis. Furthermore, the direction of research in this field is also prospected.

Key words: Metal oxide, Heterojunction, Photocatalysis, CO2 Reduction
