Comment:	2 adsorption sites of different energies, due to the presence of two crystalline phases of the oxide: α-Al2O3 and γ-Al2O3, in the amount 15 % and 85 % respectively, acidities of both sites are considered to have the same protolytic properties because only one amphoteric site is evidenced by potentiometric titration by [MCGR13].
