| 摘 要： | 本研究利用廉价过渡金属锰配合物fac-Mn(bpy)(CO)3Br和四苯基卟啉锌(ZnTPP)在可见光下催化还原CO_2.结果表明,在可见光环境下,该体系能够有效地将CO_2选择性转化为CO,而随着ZnTPP的浓度的增大,CO_2的光催化还原产物CO的产生速率和产量均有增大.当Mn(bpy)(CO)3Br与ZnTPP的浓度比为1∶2时,产物CO的转化值TON达到97.

| Abstract: | Visible light-driven photocatalytic reduction of CO2 has been investigated using abundant metal complex (fac-Mn (bpy)(CO)3Br) as catalyst and ZnTPP as photosensitizer.This photocatalytic system demonstrated high efficiency and selectivity for reducing CO2 to CO.Increasing ZnTPP concentration led to enhanced production rate and CO yield.Notably,TONco could reach 97 with a catalyst:photosensitizer concentration ratio of 1∶2. |
