Porous polymeric carbon sorbents, including particularly polymeric carbon sorbents 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 oxalate, metal acetate, metal acetyl acetonoate or mixtures thereof. By controlling the preparation, such as the temperature of preparation, the porous carbon sorbent can be controlled to be rigid/flexible. |
