摘要 本文成功利用金属中心为NiRu的NiFe氢化酶模拟物,在乙腈和水的混合溶剂中实现了人工光合成制氢。最优条件下,体系基于NiRu催化剂的产氢TON值高达1893,前10min的TOF为2.6s-1,并且通过电化学测试对催化循环过程中所生成的金属氢化物中间体进行了表征。 We had successfully fabricated a photoinduced hydrogen evolution system from a novel [NiFe]-Hydrogenase Mimic with a NiRu center in the mixture of acetonitrile and water.Under the optimal conditions,the TON value for hydrogen evolution based on the catalyst was as high as 1893,and the TOF value was2.6s-1 in the first ten minutes.Furthermore,the hydride intermidiate had been successfully observed by using electrochemical technique.
