A new powerful and oxidatively rugged pyrazolate-based water oxidation catalyst of formula {[Ru(II)(py-SO3)2(H2O)]2(μ-Mebbp)}(-), 1(H2O)2(-), has been prepared and thoroughly characterized spectroscopically and electrochemically. This new catalyst has been conceived based on a specific ligand tailoring design, so that its performance has been systematically improved. It was also demonstrated how subtle ligand modifications cause a change in the O-O bond formation mechanism, thus revealing the close activation energy barriers associated with each pathway.
一种新的基于吡唑啉酮的、强大且氧化稳定的水氧化催化剂，化学式为{[Ru(II)(py-SO3)2(H2O)]2(μ-Mebbp)}(-)，1(H2O)2(-)，已经被制备并通过光谱和电化学方法进行了全面的表征。这种新型催化剂是基于特定的配体剪裁设计构思的，因此其性能得到了系统的改进。还证明了细微的配体修饰如何改变 O-O 键形成机制，从而揭示了与每条途径相关的紧密的活化能垒。
