Template Syntheses of Porous Silica Adsorbents with Spherical Particle Morphologies

Template Syntheses of Porous Silica Adsorbents with Spherical Particle Morphologies

The peculiarities of template syntheses of ordered porous silicas with spherical particle morphologies were investigated in alkaline and acidic media. The silicas obtained were characterized by nitrogen adsorption/desorption measurements, X-ray diffraction, scanning and transmission electron microsc...
