A novel tetranuclear copper-based water oxidation catalyst was designed and synthesized by using a new multinucleating ligand containing two proton dissociation sites, 1,3-bis(6-hydroxy-2-pyridyl)-1H-pyrazole. The copper complex showed electrocatalytic activity for water oxidation reactions under aqueous basic conditions (pH 12.5) with an overpotential of approximately 500 mV. UV/Vis absorption and energy-dispersive X-ray (EDX) spectroscopic techniques coupled with electrochemical analyses of the catalyst system strongly suggest that the tetranuclear copper complex works as a homogeneous system under the conditions used. The results described here demonstrate the utility of a discrete tetranuclear copper complex in water oxidation reactions.
通过使用一种含有两个质子解离位点的新型多核配体1,3-双(6-羟基-2-吡啶基)-1H-吡唑，设计并合成了一种新型四核铜基水氧化催化剂。该铜配合物在碱性水溶液条件（pH 12.5）下对水氧化反应表现出电催化活性，过电位约为500 mV。紫外/可见吸收光谱和能量色散X射线（EDX）光谱技术与催化剂体系的电化学分析相结合，有力地表明四核铜配合物在所使用的条件下作为均相体系起作用。这里描述的结果证明了离散四核铜配合物在水氧化反应中的实用性。
