▎ 摘　　要

NOVELTY - A flower-like nickel molybdate graphene three-dimensional composite material preparing method involves preparing an aqueous solution of nickel(II) chloride, adding a sodium molybdate dihydrate and uniformly dispersing to obtain a solution A. Urea is added to the solution A to obtain solution B. The solution B is transferred to the reaction vessel, and reacted at 80-120 degrees C for 6-15 hours, filtered, and dried to obtain a flower-like nickel molybdate. Graphene oxide is ultrasonically dispersed to obtain suspension C, and added flower-like nickel molybdate to the suspension C to obtain suspension D and suspend the suspension D into the reaction vessel. The reaction is carried out at 100-180 degrees C for 8-24 hours, filtered, dried and washed to obtain the finished product. USE - Method for preparing flower-like nickel molybdate graphene three-dimensional composite material for use in supercapacitor electrode material (claimed). ADVANTAGE - The method enables preparing flower-like nickel molybdate graphene three-dimensional composite material with excellent capacitance capability and cycle performance, in environmentally-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a use of flower-like nickel molybdate graphene three-dimensional composite material.
