1 BET surface area, calculated using experimental points at relative pressures of (P/P0) 0.035–0.31, where P and P0 denote the equilibrium and saturation pressures of nitrogen, respectively; 2 Total pore volume calculated from the nitrogen volume adsorbed at P/P0 = 0.99; 3 Pore-size distribution curves were obtained from the adsorption branch using the Barrett–Joyner–Halenda (BJH) model with cylindrical pores.
