An octanuclear Cu(II) cluster [Cu₈(dpk·OH)₈(OAc)₄](ClO₄)₄ (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) was found to be an efficient catalyst for photocatalytic water oxidation. In the [Ru(bpy)₃]²⁺/Na₂S₂O₈ system, it afforded an optimal oxygen yield, turnover number (TON) and turnover frequency (TOF) of 35.6%, 178 and 3.6 s⁻¹, respectively, which are the highest values amongst all of the Cu-based photocatalytic water oxidation catalysts (WOCs).

具有生物启发性Cu ₄ O ₄立方碎片的八核Cu（ii）团簇，可实现有效的光催化水氧化†

八核Cu（II）团簇[Cu ₈（dpk·OH）₈（OAc）₄ ]（ClO ₄）₄（dpk·OH =二-2-吡啶基酮的水合宝石二醇形式的单阴离子）包含两个类似于光系统II（PSII）中的Mn ₄ CaO ₅簇的Cu ₄ O ₄立方碎片，被发现是光催化水氧化的有效催化剂。在[Ru（bpy）₃ ] ²⁺ / Na ₂ S ₂ O _8中该系统提供的最佳氧气产量，周转数（TON）和周转频率（TOF）分别为35.6％，178和3.6 s ^-1，这是所有Cu基光催化水氧化催化剂中的最高值（ WOCs）。
