USE - The method is useful for fabricating graphene ceramic nano-composite material filter for cigarette tobacco smoke. ADVANTAGE - The method produces filter i.e. cost-effective and reusable, can be plugged to any cigarette, or tobacco smoking products, provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke, adsorbs the toxic agents from the smoke (of cigarette, beedi or hookah). DETAILED DESCRIPTION - Fabricating graphene ceramic nano-composite material filter for cigarette tobacco smoke, comprises: washing ceramic material with an acid, where the acid decontaminates the surface of ceramic material, the acid activates the surface of the ceramic material, and the acid is taken in a predetermined concentration i.e. 10-60 vol.%; annealing the ceramic particles at a predetermined temperature range, where the predetermined temperature is 600-900 degrees C; coating the ceramic particles with a carbon precursor using a solvent to obtain a coated ceramic particles, where the ceramic particles are mixed with carbon precursor in a liquid phase or a dispersion phase, after mixing the carbon precursor, solvent and the ceramic particles the carbon precursor is dried by heating at a predetermined temperature range, and the concentration of carbon precursor is 5-20 wt.%; carbonizing the carbon precursor present on the surface of the ceramic particles by heating at a predetermined temperature range in air, where the heating converts the carbon precursor into an amorphous carbon, the predetermined temperature is 200-400 degrees C, and after heating the ceramic particles are obtained with a coating of amorphous carbon; segregating the ceramic particles coated with amorphous carbon based on particle size and particle shape, where the ceramic particles coated with amorphous carbon are segregated based on the particle size of 300-500 mu in diameter, and the ceramic particles coated with amorphous carbon are segregated based on a circular shape with irregular and uneven surface; annealing the ceramic particles coated with amorphous carbon at a predetermined temperature range in an inert atmospheric condition, where the annealing converts the amorphous carbon into graphene, the predetermined temperature is 600-900 degrees C, the inert atmospheric condition comprises argon, nitrogen and hydrogen, and annealing yields ceramic particles with graphene or graphene nano-composite material; chemically treating the ceramic particles with graphene or graphene ceramic nano-composite material for activation of surface, where the chemical treatment is an acid treatment, the acid is sulfuric acid, hydrochloride acid or nitric acid, acid treatment makes the graphene layers porous and increases chemisorptions or adsorption of many toxic compounds from cigarette smoke, and the toxic compounds adsorbed are ammonia, formaldehyde, mainstream total particulate matter, nicotine, tar and nitrosamines; and fabricating a tobacco smoke filter by packing the graphene ceramic nano-composite material in a casing with a pipe structure to form a filtration column, where the graphene ceramic nano-composite material is filled in an amount of 0.5-1.5 g, the graphene ceramic nano-composite material is directly filled in a granular form in the filtration column or the graphene ceramic nano-composite material is first die-compacted into a cylindrical column, the cylindrical column comprising a die compacted graphene ceramic nano-composite material is sintered, and the sintered cylindrical column comprising a die compacted graphene ceramic nano-composite material is fitted into the filtration column. An INDEPENDENT CLAIM is also included for a graphene ceramic nano-composite material filter for cigarette, comprising: a mouth piece; a filtration column, where the filtration column comprises grapheme ceramic nano-composite material; a front plug; a back plug; a cigarette holding section; and a cylindrical pipe to fix the cigarette, where the filtration column is positioned between the front plug and the back plug.
