▎ 摘　　要

NOVELTY - A modified graphene material manufacturing method involves nitrifying p-nitrochloride. 2,4-dinitrochlorobenzene and 4,4'-bipyridyl are reacted. Graphene oxide is dispersed in anhydrous ethanol. Tetramethyl-p-phenylenediamine and 1,1'-bis(2,4-dinitrophenyl)-4,4'-bipyridinium dichloride are added to dispersion liquid and precipitated. Polymer modified-graphene oxide is dispersed in ammonium molybdate saturated solution and vacuum-dried. Aqueous thioacetamide solution is added to graphene oxide-molybdate material. Graphene oxide-molybdenum sulfide material is carbonized. USE - Method for manufacturing modified graphene material that is utilized in electro-catalysis, redox catalysis and supercapacitor. ADVANTAGE - The method enables manufacturing the modified graphene material in a simple manner, with excellent electrochemical performance and large-scale production. DETAILED DESCRIPTION - A modified graphene material manufacturing method involves nitrifying p-nitrochloride to obtain 2,4-dinitrochlorobenzene. 2,4-dinitrochlorobenzene and 4,4'-bipyridyl are reacted to obtain 1,1'-bis(2,4-dinitrophenyl)-4,4'-bipyridinium dichloride (BDB). Graphene oxide is dispersed in anhydrous ethanol to obtain graphene oxide dispersion liquid. Tetramethyl-p-phenylenediamine and BDB are added to the dispersion liquid and reacted and precipitated for 24-72 hours. The obtained precipitate is washed and vacuum-dried to obtain polymer modified-graphene oxide. The polymer modified-graphene oxide is dispersed in ammonium molybdate saturated solution and reacted, filtered, washed and vacuum-dried to obtain graphene oxide-molybdate material. Aqueous thioacetamide solution is added to the graphene oxide-molybdate material. pH of the obtained mixture is regulated to alkalinity. The mixture is reacted in a hydrothermal kettle and filtered and vacuum-dried to obtain graphene oxide-molybdenum sulfide composite material. The graphene oxide-molybdenum sulfide composite material is carbonized to obtain finished product. An INDEPENDENT CLAIM is also included for a modified graphene material.
