▎ 摘  要

NOVELTY - Preparing electrode material nickel disulfido(dithioxo)molybdenum/reduced graphene oxide (GO) involves dissolving molybdate in water to prepare first solution. The sulfur source is dissolved in deionized water to form a second sulfur-containing salt solution. The second solution is added to first solution dropwise, stirred, and then cooled and crystallized the mixed solution. The anhydrous ethanol is cooled under the same conditions for suction filtration and washing to obtain tetrathiomolybdate. The nickel chloride hexahydrate is dissolved in deionized water and stirred to form nickel solution. The obtained tetrathiomolybdate is dissolved in a graphene oxide solution to obtain a mixed solution containing molybdenum sulfides. The third solution and fourth solution are continuously stirred to obtain fifth solution. The obtained fifth solution is transferred to a polytetrafluoroethylene high-pressure reactor for hydrothermal reaction. USE - Method for preparing electrode material nickel disulfido(dithioxo)molybdenum/reduced graphene oxide used as electrode material of super capacitor. ADVANTAGE - The method enables to prepare electrode material nickel disulfido(dithioxo)molybdenum/reduced graphene oxide has good electrical conductivity and long-term stability of an electric double layer capacitor with graphene, and shows good electrochemical performance. DETAILED DESCRIPTION - Preparing electrode material nickel disulfido(dithioxo)molybdenum/reduced graphene oxide (GO) for super capacitor involves dissolving molybdate in water to prepare first solution. The sulfur source is dissolved in deionized water to form a second sulfur-containing salt solution. The second solution is added to first solution dropwise, stirred, and then cooled and crystallized the mixed solution. The anhydrous ethanol is cooled under the same conditions for suction filtration and washing to obtain tetrathiomolybdate. The nickel chloride hexahydrate is dissolved in deionized water and stirred to form nickel solution. The obtained tetrathiomolybdate is dissolved in a graphene oxide solution to obtain a mixed solution containing molybdenum sulfides. The third solution and fourth solution are continuously stirred to obtain fifth solution. The obtained fifth solution is transferred to a polytetrafluoroethylene high-pressure reactor for hydrothermal reaction. The reaction product is centrifuged, washed and dried to obtain nickel disulfido(dithioxo)molybdenum/reduced graphene oxide as the electrode material of the super capacitor.
