CO_(2)还原光催化材料研究进展

Research Progress in Photocatalytic Materials for CO_(2)Reduction

太阳能驱动二氧化碳转化为可持续的碳氢燃料是缓解能源危机和全球气候变暖问题的一条重要战略途径。选择高效且经济的光催化材料是实现光催化CO_(2)转化为高附加值产物的关键。本文主要从光催化CO_(2)还原反应机理、催化剂类型等方面综述了光催化CO_(2)还原领域的研究进展,着重讨论了光催化剂改性策略,包括构筑异质结、金属掺杂、形貌调控等。目前,选择合适高效的光催化材料用以光催化CO_(2)还原制备高附加值产物等方面尚存在些许不足,比如光催化CO_(2)转化效率低、产物选择性差以及无法规模化投入生产等问题,因此如何解决上述问题是未来光催化CO_(2)资源化领域的研究重点。

Oe meaningful and strategic way to alleviate the energy crisis and global warming issues is to use hydrocarbon fuels converted using solar energy from carbon dioxide(CO_(2)).Choosing efficient and economical photocatalytic materials is the key to obtaining high-value-added products from photocatalytic CO_(2).In this article,we aim to review the research progress in the field of photocatalytic CO_(2)reduction reactions from two perspectives:reaction mechanisms and catalyst types.Emphasis is placed on the discussion of photocatalyst modification methods,including constructing hereto-junctions,metal doping,and morphology regulation.However,selecting suitable and efficient photocatalytic materials for producing high-value-added products needs to be improved.We have problems such as low CO_(2)conversion efficiency,poor selectivity of products obtained,and inability to scale up production,therefore,how to solve these problems is the focus of research in the photocatalytic CO_(2)reduction field in the future.
