摘      要：We report in situ doping of brushite on zinc manganese oxide（ZMO）, fabricated by calcining a Mn（II） oxalate‐impregnated metal‐organic framework. The doping process was conducted in com‐bination with the photocatalytic water oxidation reaction which was catalyzed by ZMO in neutral phosphate‐buffered aqueous solution containing [Ru（bpy）3]^2＋‐Na2S2O8 and calcium（II） triflate salt, exhibiting greatly enhanced water oxidation performance with optimized turnover frequency of 0.18 mmol（O2） mol（Mn）^（–1） s^（–1）. Different analytical techniques indicated that photodeposited calci‐um‐phosphate（CaP） acted as a co‐catalyst to promote the O2 evolution activity of ZMO. This system involved the use of manganese oxide and calcium ion, and the operation was conducted under am‐bient temperature and neutral conditions, thus, it efficiently mimicked the oxygen‐evolving complex in photosystem II.
