In this article we discuss those materials that have recorded the highest adsorption capacities for the greenhouse gas CO 2 under ambient conditions as well as at different temperatures and pressures. For convenience, the materials have been categorized under four categories, viz., porous carbon, metal–organic, zeolite and mesoporous silica, and porous organic frameworks. It has been found that the gas adsorption property significantly relies on several factors such as high surface area and pore volume and the presence of N ‐, O ‐ and S ‐containing moieties. The presence of a microporous structure and strong interaction between the CO 2 molecules with the framework through H ‐bonding or dipole–quadrupole interactions facilitates adsorption of the gas.
