▎ 摘　　要

NOVELTY - Preparation of doped graphene powder involves mixing magnesium powder, magnesium oxide powder and doping agent, placing the mixed powder in a sealed container, introducing carbon dioxide gas into sealed container, electrifying and heating, carrying out self-propagating synthesis to obtain the black powder, mixing the black powder with dilute acid solution, leaving still and drying. USE - Doped graphene powder. ADVANTAGE - The doped graphene powder has large specific area and pore rate, and is prepared by a simple and easy process in high yield using a wide source of raw materials. The preparation process does not cause pollution and effectively prevents the agglomeration of the powder.
