Porous properties of WP-HPPs. (a) nitrogen adsorption and desorption isotherm curves at 77 K, pore size distribution obtained from the nitrogen adsorption/desorption behaviors using the (b) DFT method (adsorption branch), (c) BJH method (desorption branch) and (d) HK method (adsorption branch), (e) pore size distribution obtained from carbon dioxide adsorption behaviors by the DFT method, and (f) carbon dioxide adsorption isotherms at 273 K.
