In heterogeneous electrocatalysts, the effect of the surface structure on water oxidation is hardly fairly compared. Herein, two manganese phosphates with identical bulk structures but different surface properties are designed to form an appealing platform to investigate the effect of the surface structure on water oxidation. The uniform MnO₆ site and similar physical properties avoid unfair comparisons of water oxidation performance. In situ Raman and X-ray absorption spectral results demonstrate that the flexibility of the catalyst surface structure and proton-accepting sites is favorable to water oxidation. The results from surface spectroscopic studies provide insights into evaluating the surface influencing factors of electrocatalytic water oxidation.

磷酸锰表面结构对电催化水氧化的影响


在多相电催化剂中，表面结构对水氧化的影响很难公平比较。在此，设计了两种具有相同本体结构但不同表面性质的磷酸锰，以形成一个有吸引力的平台来研究表面结构对水氧化的影响。均匀的MnO ₆ 位点和相似的物理性质避免了水氧化性能的不公平比较。原位拉曼和X射线吸收光谱结果表明，催化剂表面结构和质子接受位点的灵活性有利于水氧化。表面光谱研究的结果为评估电催化水氧化的表面影响因素提供了见解。
