NOVELTY - Three-dimensional graphene carbon composite desulphurizing materia comprises main ingredient of the desulphurisation material is three dimensional graphene and manganese oxide, where atomic ratio of each component Mn/C is 0.015-1.25. USE - Three-dimensional graphene carbon composite desulphurizing material. ADVANTAGE - The three-dimensional graphene carbon composite desulphurizing material which effectively improves MnO2 of load amount, make the MnO2 nanometer level dispersion, and has greatly improves desulfurization performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing three-dimensional graphene carbon composite desulphurizing material, which involves: (A) preparing three-dimensional graphene vector by taking graphite as raw material to prepare the graphene oxide solution; (B) adopting hydrothermal method to prepare three-dimensional graphene carrier is different for different concentrations of pure graphene oxide solution, selecting the threedimensional graphene structure; and (C) using ammonia water with different concentrations as additive, modifying the three-dimensional graphene in the stainless steel hydrothermal reaction kettle II, preparing composite material to obtain final product.
