NOVELTY - Preparing heterostructure catalyst by microwave method comprises (a) dispersing the reduced graphene oxide powder and ammonium tetrathiomolybdate powder in the same volume of ethanol and deionized water to obtain the corresponding dispersion, mixing the two dispersions, stirring and ultrasonically processing to obtain the mixed dispersion, (b) stirring and heating the mixed dispersion, drying to obtain a precursor powder, and tableting the precursor powder to obtain a precursor tablet, and (c) subjecting the precursor tablet to microwave radiation treatment, decomposing the ammonium tetrathiomolybdate of the precursor tablet and reacting with the graphene oxygen-containing functional group in situ, and generating molybdenum sulfide-molybdenum oxide heterostructure on the graphene sheet. USE - The heterostructure catalyst is useful in lithium-sulfur battery (claimed). ADVANTAGE - The method is short, consumes less energy, safe, simple and fast; and has a high safety factor.
