▎ 摘　　要

NOVELTY - A carbon film with non-supporting activated carbon, comprises activated carbon as basic material, and graphene as crosslinking agent. USE - Carbon film with non-supporting activated carbon, used for water treatment, drinking water purification, air purification, chemical catalysis or energy reserves application. ADVANTAGE - The carbon film is environmentally-friendly and has high adsorption performance, high chemical resistance, high corrosion resistance and high thermal stability, and removes particulate contaminant and small molecule contaminant. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of carbon film with non-supporting activated carbon; and (2) usage of carbon film with non-supporting activated carbon for water purification, air purification, chemical catalysis or energy reserves application.
