▎ 摘　　要

NOVELTY - Preparing molybdenum carbide doped linear polymer modified graphene complex comprises (i) modifying linear-linked pyridine polymer by dispersing graphene oxide in ammonium molybdate, to obtain ammonium molybdate saturated solution, refluxing the reaction solution, filtering, washing the residue with deionized water and drying under vacuum, to obtain molybdenum-containing graphene complex; and (ii) carbonizing the step (i) product under hydrogen atmosphere, to obtain the final product. USE - The graphene complex is useful in electro-catalysis, redox catalysis and super capacitor. ADVANTAGE - The product has simple preparation method, and good electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for molybdenum carbide doped linear polymer modified graphene complex, prepared as mentioned above.
