Surface areas calculated using the BET equation in the relative pressure range of 0.05–0.30.
Microporous surface areas and micropore volumes calculated using the t-plot method in the thickness range of 0.4–0.6 nm.
Single point total pore volumes determined from the N2 uptakes at relative pressures >0.995.
Mesopore diameters at the maxima of PSD curves.
The numbers in brackets are the correspondingly “hypothetical” textural parameters.
