| Abstract: | Sol-gel method with joint hydrolysis of silicon and titanium alkoxides were used to synthesize titanium-containing silica membranes on a macroporous quartz substrate. Isotherms of low-temperature adsorption-desorption of nitrogen by the samples obtained were measured. Characteristic features inherent in mesoporous samples were found in the isotherms. A change in the adsorption properties of the membranes was observed upon a preliminary treatment of the substrate with a mixture of hydrogen peroxide and concentrated sulfuric acid. |
