Abstract
Template method was used to obtain SBA-15 type mesoporous silica with monofunctional surface layer containing phosphonic acid groups [≡Si(CH2)2P(O)(OH)2] and with bifunctional surface layer of phosphonic acid and thiol groups [≡Si(CH2)2P(O)(OH)2/≡Si(CH2)3SH]. Comparison of mono- and bifunctional samples was carried out using a variety of physical and chemical methods. There was analyzed the effect of additional functional groups on the structural parameters of the samples and the effect of pH on the physical and chemical characteristics of the materials. It was shown that addition of SH groups influences the morphology and the spatial order of the porous structure of the samples.
