| 英文摘要 | an artificial photocatalytic system mimicking photosystem i (psi) has been assembled using semiconductor (cds) as photosensitizer, cobaloximes (co-iii complexes) as h-2 evolution catalysts, and triethanolamine (teoa) as sacrificial electron donor. this artificial photocatalytic system shows high hydrogen evolution activity (turnover number up to 171 based on co-iii(dmgh)(2)pycl 1) under visible light irradiation. the apparent quantum efficiency (qe) for 1/cds hybrid photocatalytic system in acetonitrile solution at 420 nm is calculated to be 9.1%. the interfacial electron transfer from photoexcited cds to co-iii complexes is very efficient through the weak adsorption of co-iii complexes on cds. the adsorption of 1 on cds in acetonitrile fits langmuir equation, the maximum monolayer adsorption capacity is 3 x 10(-3) mmol g(-1), which means most of 1 are in the solution. the rate of hydrogen production exhibits a quadratic dependence on the total concentration of i. therefore, a bimetallic catalysis pathway is proposed. the efficient electron transfer, the broad electronic absorption character of cds photosensitizer as well as the h-2 evolution ability of co-iii complexes, account for the high photocatalytic activity of this hybrid photocatalytic system.
