NOVELTY - A functionalized graphene catalyst is prepared by adding 2-5% graphite powder and nitrogen-containing conductive polymer monomer in ball milling tank; ball-milling at normal temperature and normal pressure at 300-500 rpm for 4-6 hours; transferring in sample bottle with alcohol and mixing at 4000-5000 rpm; and dissolving and dispersing using ethanol. USE - Method for preparing functionalized graphene catalyst (claimed). ADVANTAGE - The method does not use toxic chemical agent or high temperature and high pressure. It has good safety and is environment-friendly, with simple and easy operation process.
