The invention discloses a fluorine-containing porous carbon material, which belongs to the technical field of adsorption material preparation. Specifically, the fluorine-containing porous carbon material is prepared in a way that 4,4'-dibromooctafluorobiphenyl and alkyne benzene derivatives are taken as a comonomer, under the catalysis of tetrakis(triphenylphosphine)palladium (0), through Sonogashira, coupling is carried out, and high-temperature calcination is carried out at the temperature of 580-620 DEG C under nitrogen protection. The prepared fluorine-containing porous carbon material has the characteristics of large specific surface area, narrow porous distribution, high physical chemistry stability, low skeleton density and the like, and shows outstanding adsorption capacity for carbon dioxide and iodine.
