▎ 摘　　要

NOVELTY - A tobacco additive comprises dispersion of a composite material obtained by mixing an aqueous dispersion of a graphene material with an inorganic salt solution, where mass ratio of graphene is 10-45%, the graphene material is graphene oxide and is a two-dimensional layered nanometer material containing carbon and oxygen, and the concentration of the oxidized graphene water dispersion is 5-60 wt.%. USE - Tobacco additive for burning cigarettes (claimed). ADVANTAGE - The tobacco additive promotes the full combustion of the tobacco shredded tobacco, catalytic oxidation of the harmful gas, reduces emissions of harmful substances. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing tobacco additive (2) use of graphene nanocomposite-based tobacco additive for burning cigarettes.
