The surface area (SBET) was calculated with the
BET equation, the pore volume (VT) was obtained from the adsorption
isotherm at P/P0 = 0.95. The micropore area (Smic) and volume
(Vmic) were obtained using the t-plot method. The mesopore volume
(Vmes) was the deduction of Vmic from VT and the mesopore
area (Smes) was the deduction of Smic from SBET.
