光催化将二氧化碳转化为太阳能是同时解决温室效应和能源危机的有效手段。在过去的十年中，用于环境修复的铋基光催化剂经历了黄金发展时期。然而，太阳能光催化CO 2转化仅在过去五年中得到发展，并且直到现在，还没有关于铋基光催化剂对CO 2的光催化转化发表评论。本文首次综述了太阳能光催化CO2转化系统。铋基光催化剂的合成方法和光催化CO2性能，包括Sillén结构的BiOX（X = Cl，Br，I）；Aurivillius结构的Bi2 MO6（M = Mo，W）; 总结了白钨矿结构的BiVO4，Bi2 S3，BiYO3和BiOIO3。此外，审查了该光催化剂家族的活性增强策略，包括氧空位，富铋策略，刻面控制，常规II型异质结，Z型异质结和助催化剂沉积。最后，介绍了主要的力学研究方法，如原位FTIR光谱学和理论计算。讨论和总结了基于铋的光催化剂在光催化CO2转化研究中所面临的挑战和研究趋势。

Bismuth-Based Photocatalysts for Solar Photocatalytic Carbon Dioxide Conversion.

Photocatalytic CO2 conversion into solar fuels is an effective means for simultaneously solving both the greenhouse effect and energy crisis. In the past ten years, bismuth-based photocatalysts for environmental remediation have experienced a golden period of development. However, solar photocatalytic CO2 conversion has only been developed over the past five years and, until now, no reviews have been published on bismuth-based photocatalysts for the photocatalytic conversion of CO2 . For the first time, solar photocatalytic CO2 conversion systems are reviewed herein. Synthetic methods and photocatalytic CO2 performances of bismuth-based photocatalysts, including Sillén-structured BiOX (X=Cl, Br, I); Aurivillius-structured Bi2 MO6 (M=Mo, W); and Scheelite-structured BiVO4 , Bi2 S3 , BiYO3 , and BiOIO3 , are summarized. In addition, activity-enhancing strategies for this photocatalyst family, including oxygen vacancies, bismuth-rich strategy, facet control, conventional type II heterojunction, Z-scheme heterojunction, and cocatalyst deposition, are reviewed. Finally, the main mechanistic research methods, such as in situ FTIR spectroscopy and theoretical calculations, are presented. Challenges and research trends reported in studies of bismuth-based photocatalysts for photocatalytic CO2 conversion are discussed and summarized.
