NOVELTY - Preparation of three-dimensional porous molybdenum sulfide/reduced graphene oxide (MoS2/rGO) nanomaterial comprises dispersing graphene in water; adding thiourea, in which mass ratio of graphene to thiourea of (0.01-0.12):(1.0-3.0); uniformly stirring to obtain solution A; adding molybdenum trioxide to solution A; heating and evaporating while stirring to obtain preform; heating preform from room temperature to 600-800 degrees C under argon atmosphere; keeping for 2.0-4.0 hours; cooling at room temperature to obtain cooled product; washing cooled product with water; and drying to obtain three-dimensional porous MoS2/rGO nanomaterial. USE - Preparation of three-dimensional porous molybdenum sulfide/reduced graphene oxide nanomaterial used as negative electrode material for sodium ion battery (claimed). ADVANTAGE - The method produces three-dimensional porous molybdenum sulfide/reduced graphene oxide nanomaterial with excellent electrical conductivity and cycle stability, and high discharge specific capacity.
