▎ 摘　　要

NOVELTY - Preparing porous graphene using rich vitrinite bituminous coal, comprises using bituminous coal as the raw material, the coal undergoes crushing, grinding, acid washing, water washing, and drying processes to obtain a low-ash fine powder sample, the powder sample is filled into a hollow circular pore graphite crucible. The sample is then processed using a pressing tool to prepare a thin sample slice. The entire thin sample slice is irradiated with a laser under defocused and vacuum conditions to induce the formation of coal-based porous graphene material. USE - Method for preparing porous graphene by using mirror-rich bituminous coal, which is useful in photoelectric devices, electrochemical device and sensor. ADVANTAGE - The method has simple operation, economic and environment-friendly, relatively more yield. The obtained porous graphene has large specific surface area, good graphitization effect, suitable for fast production of coal-based porous graphene related material, using a new way for the utilization of coal. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a porous graphene material prepared by the method for preparing porous graphene by using mirror-rich body bituminous coal.
