▎ 摘　　要

NOVELTY - Metal salt-sulfur source composite mixed solution is prepared. 0.1-1 mg/ml graphene oxide dispersion solution is prepared. The prepared mixed solution and graphene oxide dispersion solution are mixed by ultrasonic method, to obtain dispersion solution. The obtained dispersion solution is added to atomization device provided with a cooling system, atomization is performed, obtained atomized dispersion solution is added to quartz tube furnace and thermal decomposition reaction is performed, to obtain composite nanomaterial. USE - Manufacture of composite nanomaterial (claimed). ADVANTAGE - The method efficiently provides composite nanomateiral simple and economical process in a short period of time. DETAILED DESCRIPTION - Metal salt-sulfur source composite mixed solution is prepared. 0.1-1 mg/ml graphene oxide dispersion solution is prepared. The prepared mixed solution and graphene oxide dispersion solution are mixed by ultrasonic method, to obtain dispersion solution. The obtained dispersion solution is added to atomization device provided with a cooling system, atomization is performed, obtained atomized dispersion solution is added to quartz tube furnace maintained at 500-1100 degrees C under protection of argon or nitrogen gas at gas flow rate of 0.3-1.2 L/minute and thermal decomposition reaction is performed, to obtain composite nanomaterial. The mixed solution has concentration of metal ions of 0.01-1 mol/L and mol ratio of sulfur source compound and metal ions of 1-4. The metal salt is chosen from copper, silver, zinc, cadmium, gallium, lanthanide, germanium, tin, cobalt, nickel, nitrate, acetate, chloride or sulfate.
