N2 - This letter describes an aqueous-phase synthetic route to hydrous ruthenium oxide (RuO2) nanoparticles and their conversion into crystalline ones via a thermal annealing process. Electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy were employed to characterize hydrous and crystalline RuO2nanoparticles. The hydrous RuO2nanoparticles exhibited higher activity for hydrogen evolution reaction than commercial Pt catalyst, while the crystalline RuO2nanoparticles showed better performance for oxygen evolution reaction than IrO2catalyst. With these hydrous and crystalline RuO2catalysts, we were able to achieve highly efficient overall electrochemical water splitting.
