NOVELTY - Preparing double carbon coupling molybdenum dioxide electrode material comprises dissolving phosphomolybdic acid in water to obtain first solution or dissolving hydrochloric acid and ammonium molybdate in water to obtain first solution, dispersing the liquid polymer monomer in organic solvent to obtain second solution, adding second solution to first solution and reacting to obtain phosphomolybdic acid-polymer sphere precursor, performing surface modification on phosphomolybdic acid-polymer sphere precursor to obtain phosphomolybdic acid-polymer sphere precursor with positive charge on the surface, dispersing the positively charged phosphomolybdic acid-polymer sphere precursor on surface in water, adding graphene oxide dispersion to obtain the phosphomolybdic acid-polymer sphere precursor covered by graphene oxide, and obtaining the double-carbon coupled molybdenum dioxide electrode material after calcining the graphene oxide-coated phosphomolybdic acid-polymer ball precursor. USE - The electrode material is useful in electrochemical diammoniate (claimed). ADVANTAGE - The electrode material: forms unique double-carbon coupling structure of carbon and graphene; has large specific surface area, strong interfacial interaction and high electrical conductivity; and exhibits excellent recyclability in the continuous deammonium process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for double-carbon coupled molybdenum dioxide electrode material prepared by the preparation method.
