▎ 摘　　要

NOVELTY - Graphite is added to reaction medium comprising 90-98 %mass sulfuric acid, metal or metal oxide and sulfonation reaction is carried out in presence of solid acid catalyst. 60-98 %mass nitric acid and oxidant are added to sulfonated graphite, stirred and laser ablation is carried out, to obtain suspension. Water and 25-40 %mass hydrochloric acid is added to obtained suspension and hydrolyzed to obtain metal-doped oxidized graphene. USE - Manufacture of metal-doped oxidized graphene used as intermediate for manufacturing capacitor. ADVANTAGE - The method provides metal-doped oxidized graphene having excellent electroconductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of metal non-doped reduced-type oxidized graphene, which involves heating oxidized graphene at 100-400 degrees C.
