本文首次报道了由铁络合物催化剂和介孔石墨氮化碳（mpg-C3N4）氧化还原光敏剂组成的光催化体系对CO2-to-CO的高效选择性光刺激还原。含有[Fe(qpy)(H2O)(2)](2+) （qpy = 2,2′：6′，2′：6′，2′-季吡啶）和mpg-C3N4的CH3CN/三乙乙醇胺（4:1,v/v）溶液在可见光区（λ >= 400 nm）照射，CO的选择性为97%，周转率为155，表观量子产率约为4.2%。这种混合催化系统，只包含地球丰富的元素，为利用二氧化碳作为可再生原料的太阳能燃料生产开辟了新的前景
Efficient and selective photostimulated CO2-to-CO reduction by a photocatalytic system consisting of an iron-complex catalyst and a mesoporous graphitic carbon nitride (mpg-C3N4) redox photosensitizer is reported for the first time. Irradiation in the visible region (lambda >= 400 nm) of an CH3CN/triethanolamine (4:1, v/v) solution containing [Fe(qpy)(H2O)(2)](2+) (qpy = 2,2':6',2 '':6 '',2 ''-quaterpyridine) and mpg-C3N4 resulted in CO evolution with 97% selectivity, a turnover number of 155, and an apparent quantum yield of ca. 4.2%. This hybrid catalytic system, comprising only earth abundant elements, opens new perspectives for solar fuels production using CO2 as a renewable feedstock
