综述了使用金属配合物，特别是铼(I)联吡啶配合物的高效光催化二氧化碳还原。从全球变暖问题和化石燃料短缺两个角度解释了开发这种二氧化碳减排光催化剂的重要性。近年来，利用以下系统和方法在光催化剂CO2还原方面取得了进展：（1）在铼（I）单核配合物中引入膦配体，（2）两种铼（I）配合物的混合体系，其中CO2还原的量子产率高达59％，（3）在铼（I）配合物中引入配体间弱相互作用（π-π和CH-π），（4）超分子由 Ru(II) 和 Re(I) 配合物构成的光催化剂，可以有效地利用各种可见光。
Highly efficient photocatalytic CO2 reduction using metal complexes, particularly rhenium(I) bipyridine complexes, is reviewed. Importance about development of such CO2 reduction photocatalysts is explained from the points of both problems with global warming and shortage of fossil fuels. Recent progress in photocatalysts for CO2 reduction has been achieved using the following systems and methods: (1) introduction of a phosphine ligand to rhenium(I) mononuclear complexes, (2) a mixed system of two rhenium(I) complexes, of which quantum yield for CO2 reduction reaches up to 59%, (3) introduction of interligand weak (π-π and CH-π) interaction into rhenium(I) complexes, and (4) supramolecular photocatalysts constructed with both Ru(II) and Re(I) complexes, which can efficiently use a wide range of visible light.
