Graphite oxide is prepared first with a modified Hummers process; the strong oxidants, such as concentrated sulfuric acid, sodium nitrate and potassium permanganate, are subjected to low-temperature, medium-temperature and high-temperature reactions to oxidize graphite into graphite oxide; a simple one-step hydrothermal process is utilized at a relatively low temperature to subject the prepared graphite oxide to ultrasonic stripping so as to obtain graphene oxide; the graphene oxide is effectively mixed with a molybdenum source and a sulfur source, the mixture is dispersed well, and reduced graphene oxide-carrying molybdenum disulfide composite is synthesized finally under hydrothermal
