Copper(I) cysteine complexes: efficient earth-abundant oxidation co-catalysts for visible light-driven photocatalytic H2 production

Author affiliations

Abstract

A copper(I) cysteine complex generated by mixing Cu(II) ions with cysteine in aqueous solution greatly enhanced the activity of CdSe photocatalysts for H2 production in aqueous solution under visible light excitation. The complex can enhance the H2 evolution rate by as much as 150 times, by acting as an oxidation co-catalyst and increasing charge carrier lifetimes. The copper(I) cysteine complex can also be applied to enhance the H2 production performance of other semiconductor photocatalyst systems, thereby affording a new research direction in the development of co-catalysts for solar hydrogen production.
