NOVELTY - Molybdenum disulfide-carbide double-layer hollow ball with high specific surface area where morphology of the molybdenum disulfide-carbide double-layer hollow sphere is a double-layer hollow structure of molybdenum disulfide-coated carbon spheres, and the average size of the molybdenum disulfide- carbide double-layer hollow sphere is 1-2 μm. The mass percentage content of carbon in the molybdenum disulfide-carbide double-layer hollow sphere is 1-10%, and molybdenum disulfide (remaining amount). USE - The molybdenum disulfide-carbide double-layer hollow ball with high specific surface area is useful for preparing photo-catalyst/capacitance absorption synchronous electrode material (claimed). ADVANTAGE - The molybdenum disulfide-carbide double-layer hollow spheres can ensure a good combination of molybdenum disulfide and carbon, and exert the synergistic effect of molybdenum disulfide and carbon, in which the silicon dioxide nanospheres play the role of a hard template, facilitates the growth of carbon nanoparticles on surface, is helpful to control the structure and morphology of the hollow spheres, so that the generated molybdenum disulfide-carbide double-layer hollow spheres have a uniform shape and ensure the uniformity of the photocatalytic/capacitive adsorption effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of molybdenum disulfide- carbide double-layer hollow ball with high specific surface area, comprising (i) adding sequentially deionized water, ethanol, tetraethyl orthosilicate and aqueous ammonia, vigorously stirring for 25 minutes at room temperature, stirring for a period of time, the solution is gradually changed from transparent to milky white to obtain silicon dioxide nano-sphere; (ii) using silicon dioxide nanospheres prepared in step (i) as templates, dispersing the carbon source, sulfur source, molybdenum source and reducing agent in the organic solvent, continuously stirring for 24 hours under the light condition, transferring into the reaction kettle, after hydrothermal reaction, acidifying and etching to obtain molybdenum disulfide- carbide hollow ball; (ii) using molybdenum disulfide- carbide hollow ball prepared in step (ii) as template, dispersing the carbon source, sulfur source and molybdenum source in the organic solvent, continuously stirring for 24 hours under the dark condition, transferring into the reaction kettle, and placing in the vacuum drying box for hydrothermal reaction to obtain molybdenum disulfide- carbide double-layer hollow ball.
