[a] Only by ECA. [b] From inductively coupled plasma optical emission spectroscopy (ICP‐OES). [c] Specific surface area obtained by applying the Brunauer‐Emmett‐Teller (BET) method to N2 adsorption isotherms at 77 K. [d] Total pore volume (V T ) calculated by DFT, in parentheses the result obtained at P/P 0=0.95. [e] Pore diameter as obtained from QSDT method applied to N2 adsorption isotherms at 77 K (in parentheses the values obtained applying the same model to Ar adsorption isotherms at 87 K). [f] Amount of CO2 adsorbed at 273 K at 800 torr.
