| Abstract: | Studies have been made on the effects of template synthesis conditions (initial substances, SA/TiO2 ratio, and pH) on TiO2 gel formation; under certain conditions, a nanoperiodic structure is formed in the presence of a cationic surfactant SA (ethonium, cetyltrimethylammonium chloride) and in the presence of anionic SA (sodium dodecylsulfat, and dodecylbenzenesulfonic acid). A feature of the TiO2 gels made in the presence of a crown ether (dibenzo-18-crown-6) is that it contains a nanoperiodic structure and a crystalline one (anatase). L. V.
