摘要:The development of efficient molecular catalysts for visible-light driven CO2reduction, based on abundant materials, is necessary to meet energy demands and address environment problems. In this work, a Co(bpy)2Cl2catalyst was developed and showed high efficiency and durability for the photocatalytic reduction of CO2and protons. Yields of CO and H2as high as 62.3 and 69.9 µmol were achieved and the turnover numbers (TONs) reached 6230 and 6990, respectively, under light irradiation (λ > 420 nm) for 4 h, indicating that the mixture gases could be a candidate as syngas. The apparent quantum yield was determined to be 2.1% for CO. Mechanistic studies revealed oxidative quenching of the photosensitizer Ru(bpy)3Cl2by the catalyst. The photocatalytic performance, flexible synthesis and non-noble metal catalyst in our system show great promise for the practical application of Co(bpy)2Cl2to photocatalytic reduction of CO2. © 2017 Science Press
