Abstract: A method for preparing a cobalt sulfide/reduced graphite oxide composite includes: preparing a glycerol-cobalt precursor by taking a water-soluble cobalt salt, a micromolecular alcohol solvent, and glycerol as raw materials; mixing the glycerol-cobalt precursor with an alkali liquor to prepare a Co(OH)2 nanoflower; calcining the Co(OH)2 nanoflower to obtain a Co3O4 nanoflower; subjecting the Co3O4 nanoflower to a reaction with a water-soluble sulfur salt to obtain a COS nanoflower, and mixing the COS nanoflower with graphite oxide and carrying out a heat treatment to obtain the composite. The response characteristics of a gas sensor to NO2 gas are studied at room temperature, and the graphite is complexed with a transition metal sulfide with unique morphology to construct a unique heterostructure. While expanding the specific surface area to increase the number of adsorption sites, the heterostructure of a contact surface is used to greatly enhance the charge-transfer efficiency.
