Metal-doped ruthenium oxide nanometer material, and preparation method and use thereof

Abstract

The disclosure relates to a metal-doped ruthenium oxide nanometer material and methods of its preparation and use. The metal-doped ruthenium oxide nanometer material may be an acid-insoluble metal oxide-doped ruthenium oxide nanometer material or a transition metal-doped ruthenium oxide nanometer material. The molecular formula of the metal-doped ruthenium oxide nanometer material is MxRu1-xO2, wherein M is selected from niobium, titanium, zirconium, hafnium, tungsten, molybdenum, and tantalum; or a transition metal selected from Cr, Mn, Ge, In, Sn, Sb, Nb, Ti, Zr, Hf, W, Mo, Ta, and Pt. The dopant metal is highly uniformly dispersed in a ruthenium oxide material, such that active-site ruthenium is well controlled, and the stability and activity of the material during an oxygen evolving reaction in water hydrolysis are improved.
