▎ 摘　　要

NOVELTY - Preparing binary doped graphene comprises transforming doped source and mixture of organic salt, heating the mixture to 400-1600 degrees C in a non-oxidizing atmosphere to obtain a binary-doped graphene-mixed metal oxide. The doped source is boron source, nitrogen source, phosphorus source or sulfur source. The organic salt is magnesium, calcium, strontium, barium, cobalt, nickel, manganese, iron, zinc, aluminum, indium, bismuth citrate, gluconate, tartrate, threonate, n-alkyl fatty acid salt or oleate. USE - The method is useful for preparing binary doped graphene (claimed), which is useful in a lithium ion battery, a super capacitor, a lead-acid battery, water treatment, electric catalysis, and photocatalysis fields. ADVANTAGE - The method is capable of simply and rapidly preparing the binary doped graphene without agglomeration.
