Interfacial Coordinative Photoelectrochemistry for Energy Conversion and Catalysis

抄録

In order to induce by light demanding interfacial reactions for energy conversion and catalysis, it is generally not sufficient to provide photoexcited electrons for tunnelling processes. Multi-electron transfer processes and efficient catalytic mechanisms require specific chemical bonding conditions. It is therefore reasonable to develop photoactive materials which transfer electronic charge carriers via states of transition metals, which can induce coordination chemical mechanisms. Experimental evidence that this strategy is feasible is presented on the basis of photoelectrochemical experiments with FeS₂ and oxygen reduction catalysis with transition metal cluster compounds of the composition (M, Mo) ₆X8 with X=S, Se and M=transition metal.
