Carbonaceous porous materials derived from leather skin residues have been
found to have excellent CO2 adsorption properties, with interestingly high gas selectivities
for CO2 (α > 200 at a gas composition of 15% CO2/85% N2, 273K, 1 bar) and capacities
(>2 mmol·g−1 at 273 K). Both CO2 isotherms and the high heat of adsorption pointed to the
presence of strong binding sites for CO2 which may be correlated with both: N content in the
leather residues and ultrasmall pore sizes.
