Under mild conditions (near-neutral aqueous solutions, room temperature, and atmospheric pressure), an attractive electrolyte was expanded for splitting water and three novel oxygen-evolution catalysts (Co-Ci, Ni-Ci, Ag-Ci) were generated. The Co-Cicatalyst showed a high oxygen-evolution rate (24.42 μmol h−1), a low oxygen-evolution overpotential (395 mV) and excellent stability. In addition, the non-amorphous Ag-Cicatalyst, different from reported catalyst, was generated. The catalyst has been further characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), and X-ray photoelectron spectroscopy (XPS).
