The oxygen-evolving center (OEC) in photosystem II (PSII) is a unique biological catalyst that splits water into electrons, protons, and O by using solar energy. Recent crystallographic studies have revealed that the structure of the OEC is an asymmetric Mn Ca cluster, which provides a blueprint to develop man-made water-splitting catalysts for artificial photosynthesis. Although it is a great challenge to mimic the whole structure and function of the OEC in the laboratory, significant advances have recently been achieved. In this Minireview, recent progress on mimicking the natural OEC is discussed. New strategies are suggested to construct more stable and efficient new generation of catalytic materials for the water splitting reaction based on the artificial Mn Ca cluster in the future.
光合作用系统 II 中的氧析出中心（OEC）是一种独特的生物催化剂，它利用太阳能将水分解为电子、质子和 O。最近的晶体学研究揭示了 OEC 的结构是一个不对称的 MnCa 簇，这为开发用于人工光合作用的人造水分解催化剂提供了蓝图。尽管在实验室中模拟 OEC 的整体结构和功能是一个巨大的挑战，但最近已经取得了重大进展。在这篇综述中，讨论了模拟天然 OEC 的最新进展。根据未来人工 MnCa 簇，提出了构建更稳定、更高效的新一代水分解反应催化材料的新策略。
