Abstract Reduction of CO2 using a heterogeneous photocatalyst under visible light has been studied as a potential means to address the problems of global warming and the depletion of fossil fuels. Recently, hybrid photocatalysts constructed with a metal complex and a particulate semiconductor are of particular interest because of the excellent electrochemical (and/or photocatalytic) ability of the metal complexes for CO2 reduction and the high efficiency of the semiconductors for oxidation reactions, where the ultimate target of oxidation reaction is water oxidation to form molecular O2. This review article highlights our recent progress in the development of metal-complex/semiconductor hybrid materials for visible-light CO2 reduction with a focus on oxynitride and nitride materials as the semiconductor component.

在可见光下使用氧氮化物和氮化物还原 CO 2

摘要 在可见光下使用多相光催化剂减少 CO2 已被研究作为解决全球变暖和化石燃料枯竭问题的潜在手段。最近，由于金属配合物对 CO2 还原的优异电化学（和/或光催化）能力和半导体在氧化反应中的高效率，由金属配合物和颗粒半导体构成的混合光催化剂特别受关注。氧化反应的目标是水氧化形成分子O2。这篇评论文章重点介绍了我们在开发用于可见光 CO2 还原的金属-复合物/半导体混合材料方面的最新进展，重点是作为半导体组件的氮氧化物和氮化物材料。
