摘要： 利用2-羟基-3-甲氧基苯甲醛和2-氨基-3-苯基丙醇为原料制备了一种具有立方烷构型的四核金属配合物Cu4，并对该配合物在均相条件下的电催化水氧化性能进行了系统研究，结果表明，Cu4具有较高的催化水氧化活性，在1.75 V时催化水氧化的周转频率(TOF)达到119 s-1，法拉第效率为88.2%.出色的电催化性能可以归因于Cu4中易于暴露的双金属协同催化活性位点，显著提高催化效率的同时又避免了高价金属中间体的形成.本研究不仅为深入理解水氧化的多电子多质子催化过程提供了重要线索，同时也证明了多金属协同催化策略在调控O-O键形成方式上的有效性，为设计新一代高效水氧化催化剂提供了新的视角和策略.

Abstract: A cubane-like tetranuclear copper(II) complex Cu4 was synthesized using 2-hydroxy-3-methoxybenzaldehyde and 2-amino-3-phenylpropanol as ligands. Its performance as a homogeneous electrocatalyst for the water oxidation reaction was systematically evaluated. Cu4 exhibited high catalytic activity, achieving a remarkable turnover frequency (TOF) of 119 s-1 at an applied potential of 1.75 V (vs. NHE) with a Faradaic efficiency of 88.2%. This high performance is attributed to the readily accessible bimetallic synergistic catalytic sites within the Cu4 core. These sites facilitate efficient catalysis while circumventing the formation of high-valent metal intermediates. This study provides insights into the multi-electron/multi-proton processes of water oxidation and demonstrates the effectiveness of a polymetallic cooperative strategy in modulating O-O bond formation, offering new perspectives for designing next-generation efficient water oxidation catalysts.
