Abstract

Mesoporous silica materials SBA-15 with tunable microporosity were synthesized starting from sodium silicate solutions and triblock copolymer surfactants Pluronic 123 (EO20PO70EO20, M av = 5800). Microporosity within the ordered mesoporous silica SBA-15, confirmed by physisorption, could be controlled by varying H +/Si molar ratios (pH value) of synthetic gel. The fraction of the micropore volume in the total volume can be adjusted up to 0.22.
