N₂ adsorption-desorption isotherm (a) of different samples at 77 K with corresponding pore size distributions (b) calculated by Barrett-Joyner-Halenda (BJH) method from desorption branch. All adsorption-desorption isotherm curves in (a) are added some units along the volume adsorbed axis (Y axis) in order to observe clearly. (■) Sample H, (●) Sample F, (▲) Sample B, and (▼) Sample G.
