Porous polymeric carbon sorbents, including particularly polymeric carbon sorbents for CO2 capture for flue gas from power plants, for gases from other post combustion CO2 emission outlets, for gas storage, for direct air capture of CO2, and methods of making and using same. The porous carbon material can be prepared by heating plastic with an additive. The additive can be selected from metal hydroxide, metal carbonate, metal bicarbonate, metal oxalate, metal acetate, metal acetylacetonoate or mixtures thereof. By controlling the preparation, such as the temperature of preparation, the porous carbon sorbent can be controlled to be rigid or flexible. |
