Abstract: Carbon materials with stable physicochemical properties, high surface area and abundant active adsorption sites can be widely used in waste gas adsorption, water treatment, solvent recovery and other fields. The preparation methods, gas adsorption properties and usesof five carbon materials,activated carbons, activated carbon fibers, carbon nanofibers, carbon nanotubes and graphene,in air purification are summarized. Traditional carbon materials and their modified products and composites have excellent adsorption performance for waste gases. Nano-carbon materials have not only excellent potential applications, but also electrical properties that can be used to produce gas sensorsfor monitoringair pollution.
