▎ 摘 要
NOVELTY - A graphene-modified activated carbon is prepared by immersing activated carbon in an aqueous solution of oxidized graphene deionized water to obtain mixture, stirring the mixture at room temperature and drying to obtain a graphene-modified activated carbon, where the activated carbon and the oxidized graphene in a mass ratio of 1: 1-100. USE - Graphene-modified activated carbon for use in super capacitor electrode. ADVANTAGE - The graphene-modified activated carbon can be prepared with better energy-saving in a simple, eco-friendly and cost effective manner.
