The research described in this thesis deals with the synthesis and properties of ceramic oxide membrane materials. Since most of the currently available inorganic membranes with required separation properties have limited reliability and long-term stability, membranes made of new oxide materials that can improve their performance are developed. Anatase and amorphous titania were chosen as mesoporous and microporous material for membrane development, respectively. The relationship between synthesis conditions and properties of the obtained materials could be understood by applying the theory of sol-gel chemistry of transition-metal alkoxides. The developed membrane systems containing Al2O3, SiO2 and TiO2 were evaluated regarding their potential for application in gas separation, nanofiltration and pervaporation.
