▎ 摘　　要

NOVELTY - The method involves (i) placing graphite oxide and grinding balls into a grinding tank, and vacuumizing the grinding tank after sealing, (ii) charging hydrogen sulfide gas into the grinding tank, and (iii) installing the grinding tank on a planetary ball mill for grinding to obtain sulfur-oxygen co-doped graphene, where the material of grinding ball and the grinding tank is agate material. USE - The method is useful for preparing sulfur-oxygen co-doped graphene (claimed). ADVANTAGE - The method has simple process, no heating, no separation, purification and impurity removal, and high yield.
