▎ 摘　　要

NOVELTY - Preparing phosphorus-doped graphene comprises (i) ultrasonically stripping graphite oxide in solvent to obtain graphene oxide solution, (ii) mixing graphene oxide solution and phosphorus containing compound, and dispersing ultrasonically to obtain liquid mixture, drying liquid mixture to obtain solid mixture, (iii) subjecting the solid mixture to a temperature-programmed heat treatment under an inert gas atmosphere to obtain final product. USE - The method is useful in preparing phosphorus-doped graphene (claimed). ADVANTAGE - The method is suitable for large scale industrial production.
