The synergistic catalysis of bimetallic catalysts is one of the important ways to improve the catalytic performance; therefore, the development of efficient bimetallic water oxidation catalysts (WOCs) has received extensive attention. This work proposed a bimetallic Fe 3 O 4 /CuO catalyst prepared in situ from the Cu−Fe Prussian blue analogues precursor, promoting Fe 3 O 4modified CuO as a highly efficient and stable bimetallic WOC. The Fe 3 O 4 /CuO exhibits superior and robust catalytic activity for the oxidation of water. Compared with the reported results, it has a higher O 2 evolution rate of about 4406 μmol•h −1 •g −1 and a maximum value for the yield of O 2 as 83.2%, mainly because of the synergetic effect between Fe 3 O 4 and CuO in the complicated water oxidation reaction (WOR) process. We hope this work will be useful for other researchers to design new transition metal bimetallic catalysts for WOR.
