Kukh A. Novel composite adsorbent-photocatalyst based on titanium (IV) oxide

The dissertation is devoted to the synthesis and study of pure titanium (IV) oxide and composites with activated carbon. For the first time, using a precursor titanium (III) sulfate by a low-temperature sol-gel method without following heat treatment, a titanium (IV) oxide photocatalyst and an adsorbent-photocatalyst activated carbon – TiO2 were synthesized and their complete characterization was carried out. A laboratory procedure for the synthesis of a photocatalyst of titanium (IV) oxide and an adsorbent-photocatalyst activated carbon - TiO2 using a titanium (III) sulfate precursor by low-temperature sol-gel method without following heat treatment has been developed. It has been proven that TiO2-based photocatalyst adsorbents synthesized by low-temperature hydrolysis of titanium (III) sulfate are effective in the processes of adsorptive removal and photocatalytic decomposition of dyes and pharmaceutical substances. It has been established that they can be recommended for use in pharmaceutical wastewater treatment technologies.
