Abstract

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.
