▎ 摘　　要

NOVELTY - Preparation of porous graphene derivatives involves dispersing graphene derivatives and biodegradables in buffer solution, mixing, stirring for certain time under temperature and pressure environment to satisfies the activity of the biodegradables to obtain mixture, subjecting the obtained mixture to centrifugal washing and drying. USE - Preparation of porous graphene derivatives (claimed). ADVANTAGE - The prepared porous graphene derivatives has different pore sizes, different pore distributions, different pore contents, and different oxygen-containing functional groups. The method is simple, safe, economical, environmentally friendly, stable, and easy to control.
