An octanuclear Cu(II) cluster with bio-inspired Cu4O4 cubic fragment for efficient photocatalytic water oxidation

Abstract

An octanuclear Cu(II) cluster [Cu8(dpk•OH)8(OAc)4](ClO4)4 (1, dpk•OH = the monoanion of the hydrated, gem-diol form of di-2-pyridyl ketone) that contains two Cu4O4 cubic fragments similar to the Mn4CaO5 cluster in photosystem II (PSII) is found to be an efficient catalyst for photocatalytic water oxidation. In [Ru(bpy)3]2+/Na2S2O8 system, it affords optimal oxygen yield, turnover number (TON) and turnover frequency (TOF) of 35.6%, 178 and 3.6 s-1, respectively, which are the highest value among all the Cu-based photocatalytic water oxidation catalysts (WOCs).
