The effect of hydrophilic agent on pores and walls of SBA-16 type mesoporous silica
The ordered mesoporous SBA-16 materials with cubic Im3m symmetry were successfully synthesized by using the mixture of triblock copolymer surfactant (Pluronic F127) and Dglucose as a structure directing agent and a hydrophilic wall modifier, respectively. The materials were characterized with complementary combination of powder X-ray diffraction, transmission electron microscopy and nitrogen adsorption and desorption study. The wall thicknesses of the materials were decreased as the increases of mesoporosities by varying the weight ratios of F127 to D-glucose. The improved hydrothermal stability of the materials was confirmed by powder X-ray diffraction analysis after the materials were refluxed in boiling water for prolonged periods.
