Development and sorption characterization of some model mesoporous and microporous silica adsorbents

Mesoporous and microporous silica substrates were prepared via sol-gel and micelle templating and characterized through N2 sorption. Materials consisting of: cage-like cavities interconnected by narrow throats (SBA-16), individual cylindrical pores of about the same size (SBA-15), sinuous ganglion-like sequences of bulges and throats (mesoporous glass), and nanoparticle arrangements (microporous SiO2) were studied by remarking their outstanding morphological and sorption qualities.
