The mesoporous silicas with the thiourea functional group Si(CH2)3NHC(S)NHC2H5 were synthesized using the template method (template is cetylpyridinium chloride, C16PyCl). The aim of this research was to study the influence of a number of factors on mesoporous silicas structure: the concentration of alkoxysilanes and micelle-forming surfactant; the ratio of alkoxysilanes and the nature ofmedium in hydrothermal treatment of mesophases. The optimum conditions for synthesis of mesoporous silicas which had been functionalized by thiourea groups and which had a highly ordered hexagonal structure were found.
