Textural characterization of the synthesized samples was
determined by N2 and CO2 adsorption/desorption measurements
at 196 C and 0 C, respectively. Gas adsorption measurements
were performed in a homemade fully automated manometric
equipment. Before any adsorption experiment, samples were degassed
at 250 C for 4 h. The pore size distribution was calculated
from the nitrogen adsorption data using the NLDFT
model (Non Localized Density Functional Theory) based on a
cylindrical pore-equilibrium model.
