High-current density (≥1 A cm–2) is a critical factor for large-scale industrial application of water-splitting electrocatalysts, especially seawater-splitting. However, it still remains great challenge to reach high-current due the lack active and stable intrinsic catalytic sites in catalysts.

Abstract Efficient molecular oxygen activation is crucial for catalytic oxidation reaction, but highly depends on the construction of active sites. In this study, we demonstrate that dual adjacent Fe atoms anchored MnO 2 can assemble into a diatomic site, also called as -hosted dimer, which activates to form an intermediate species Fe(O = O)Fe efficient CO oxidation. These single-atom sites exhibit stronger O performance than conventional surface vacancy This work sheds light mechanisms...
