▎ 摘　　要

NOVELTY - A ferric oxide nanosheet/graphene composite electrode material preparing method involves separately disposing 0.05-5 mol/L ferrous sulfate heptahydrate solution and 1-10 mg/ml graphene dispersion, slowly adding ferrous sulfate heptahydrate solution to the graphene dispersion, placing in water bath for carrying out ultrasonic treatment for 30 minutes to form a uniform solution. The uniform solution is added with precipitating agent at a dropping rate of 0.01-5 ml/minute, stirred for 30 minutes, added with 3 ml hydrogen peroxide dropwise and stirred for 20 minutes to obtain a mixed solution. The mixed solution is injected into a 100 ml high-pressure reaction vessel of PTFE, and reacted at a temperature of 50-200 degrees C for 10 hours to obtain the finished product. USE - Method for preparing ferric oxide nanosheet/graphene composite electrode material. ADVANTAGE - The method enables preparing ferric oxide nanosheet/graphene composite electrode material with improved transmission efficiency of the charge material and the bonding effect of the base material of ferric oxide nano sheet uniform growth on the graphene surface, enhanced conductivity and better practical value.
