(a) Schematic illustration of O and N interaction sites in porous carbon and (b) corresponding binding energy of C₂H₄/C₂H₆ with different interaction sites. (c) FTIR spectra of samples [30]. (d) Interaction between C₂H₄/C₂H₆ and the Csp² and N/O-Csp² single layers. (e) The interaction energy between C₂H₄/C₂H₆ and different pore sizes of Csp² and N/O-Csp² double carbon layer is referred to as that of the Csp², N/O-Csp² single carbon layers [98]. (f) Schematic structures and Schwarzite models of samples. (g) Adsorption isotherms of beta-ZTC at 303 K [96].
