Effect of template nature and drying temperature on silica gel structure

Abstract

A number of silica gel samples have been prepared by the template method, using salts as templates. Some of salt reinforce the solvent microstructure, while other, on the contrary, destroy it. In addition, during SiO2 samples drying, salt crystals are formed acting as templates. It has been shown that the sorption capacity of samples obtained in the presence Na2SO4 template, is greater by 173% than for the control sample. On the contrary, the sorption capacity of samples synthesized in presence of RbBr is almost the same as for the the control sample. It has been found that the hydroxide deposition method has a significant impact on the structure of samples and homogeneity of their porosity.
