▎ 摘　　要

NOVELTY - Preparing graphene embedded monodisperse metal atom, comprises (i) adding graphite-based materials and grinding balls into milling pot under inert gas protection; (ii) placing the milling jar on a planetary ball mill, and milling for 2-50 hours; (iii) adding metal phthalocyanine compound under inert gas protection into the obtained sample of step (ii), and milling for 2-50 hours; and (iv) separating the grinding ball and sample. USE - The method is useful for preparing graphene embedded monodisperse metal atom (claimed).
