▎ 摘　　要

NOVELTY - The method comprises (a) adding thioacetamide and small molecular alcohol to the aqueous dispersion of graphene oxide, and mixing to obtain a mixture A, (b) heating the mixture A to obtain mixture B, and (c) removing impurities of the mixture B to obtain sulfur-doped graphene oxide. USE - Method for preparing graphene material with high sulfur atom doping degree, which can be used as a carrier for electrocatalysts for proton exchange membrane fuel cells, and methanol fuel cells. ADVANTAGE - The method has low preparation cost, simple operation and mild reaction conditions; enhances electrical conductivity; improves the electrochemical stability; makes the graphene material in the actual application field has a wider prospect; and realizes batch production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene material with high sulfur atom doping degree.
