▎ 摘　　要

NOVELTY - A graphene adsorbent material comprises fibrous support, carrier fiber, and graphene doping element, where doping element is aluminum, silicon, and/or iron. USE - Graphene adsorption material used for flue gas filtering apparatus, particularly cigarette filter, air conditioner filter core, or automobile exhaust gas device (claimed). ADVANTAGE - The material adsorbs and filters fused ring aromatic hydrocarbon such as benzopyrene and harmful substances, retains nicotine and other harmless substances, decreases smoking danger, has alcohol taste, promotes pleasant sensation, and prevents environmental factors such as cigarette damp moldy phenomenon. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene adsorbent material comprising contacting fibers with graphene material containing graphene and doping element.
