The invention provides a method for preparing a graphene-like molybdenum disulfide-ferroferric oxide composite material through reduction for organic carbon of saccharides. The method comprises the following steps: adding a molybdenum disulfide powder in an intercalation solution and carrying out an intercalation reaction, and filtering and drying after the reaction is finished to obtain an intercalation molybdenum disulfide powder; mixing the intercalation molybdenum disulfide powder prepared in the step 1 with the organic carbon of the saccharides and water, uniformly stirring, drying and grinding to obtain a precursor powder; mixing ferric nitrate with citric acid and then adding the mixture in water, and carrying out a chelation reaction to obtain a yellow sol solution; adding the precursor powder in the yellow sol solution, stirring and mixing to obtain a mixed gel, drying and grinding to obtain a dry gel powder; and carrying out a reduction reaction on the dry gel powder under a protective gas, cooling after the reaction is complete, and taking out a reaction product. The method provided by the invention realizes peeling for molybdenum disulfide and generation for ferroferric oxide simultaneously, and finishes a compounding process of graphene-like molybdenum disulfide and ferroferric oxide in one step.
