▎ 摘　　要

NOVELTY - Graphene adsorbent material comprises fiber carrier, and graphene and doped elements supported on the fiber carrier, where the doping element is aluminum, silicon and/or iron, and the doping element content is 0.002-1 wt.% of the fiber carrier. USE - The graphene adsorbent material is useful for flue gas filtration device (claimed). ADVANTAGE - The graphene adsorbent material prevents the damp environment factors including cigarette mildewing phenomena. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparation of graphene adsorbent comprising contacting fiber carrier and graphene material to obtain final product, where the graphene material is graphene and doping elements; (2) use of graphene adsorbent material for flue gas filtration device, where flue gas filtration device comprising a cigarette filter, an air conditioning filter, or a vehicle exhaust; and (3) cigarette filter comprising graphene adsorbent material.
