(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].
