摘要：The photocatalytic conversion of CO2 to fuels by light is of research interest owing to its relevance to environment and energy concerns. In this work, a hybrid H-TiO2-rGO-Re(bpy)(CO)(3)Cl composite consisting of a rhenium 2,2-bipyridine compound, Re(bpy)(CO)(3)Cl, which was covalently grafted on reduced graphene oxide (rGO) and hydrogenated TiO2 (H-TiO2) was prepared. H-TiO2-rGO-Re(bpy)(CO)(3)Cl demonstrated high efficiency for visible light photo-conversion of CO2 into CO in triethanolamine/N,N-dimethylformamide (V:V=1:9) solution with total turnover numbers larger than 580. In addition, the composite showed high stability with no leveling-off tendency after four catalytic experimental runs. The experimental results indicate that the suitable assembly of the Re(bpy)(CO)(3)Cl, rGO, and H-TiO2 components in the H-TiO2-rGO-Re(bpy)(CO)(3)Cl composite is necessary for the observed high performance of the catalyst for CO2 reduction under visible light irradiation.
