Abstract
The microporosity, surface area and surface fractal dimension of several silica Aerogels are determined by means of the analysis of N2 (77 K), Ar (77 K) and CO2 (273 K) adsorption isotherms. The role of the pH conditions during the preparation and the effect of the rehydroxylation on the microporous texture are evidenced. The value of the molecular area of N2 on hydroxylated surfaces and the mechanism of the secondary micropore filling are discussed.
