Preparation method of graphene supported ruthenium oxide electrode materials



The invention provides a preparation method of graphene supported ruthenium oxide electrode materials, which comprises the following steps of: adding sodium hydroxide into graphite oxide colloid subjected to ultrasonic stripping to regulate the pH value; dripping the regulated graphite oxide colloid into a water-containing ruthenium trichloride solution; then, adding sodium hydroxide into the mixed solution to regulate the pH value to 7; filtering materials after hydro-thermal treatment; drying the materials after water washing; and obtaining the graphene supported ruthenium oxide super capacitor electrode materials after low-temperature calcinations.
