一种石墨烯负载氧化钌的电极材料的制备方法

Abstract

一种石墨烯负载氧化钌电极材料的制备方法,将氢氧化钠加入到经超声剥离的氧化石墨胶体中调节pH值,将调节后的氧化石墨胶体逐滴加入到含水三氯化钌溶液,在混合液中再加入氢氧化钠调节pH值到7,水热后过滤,用水洗涤后干燥,低温煅烧后获得石墨烯负载氧化钌超级电容器电极材料。
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.
