制备了三组分均相催化剂体系，其中IrIII络合物作为光敏剂，具有二铁核和树枝状骨架的人工氢化酶作为质子还原催化剂，三乙胺作为牺牲电子供体。初始转换频率超过7240 h-1，量子产率高达28%，被确定为光催化析氢。
A three‐component homogeneous catalyst system has been prepared with an IrIII complex as the photosensitizer, artificial hydrogenases bearing a diiron core and dendritic frameworks as the proton reduction catalyst, and triethylamine as the sacrificial electron donor. An initial turnover frequency of over 7240 h− 1 and a quantum yield of up to 28% were determined for the photocatalytic evolution of hydrogen.
