Synthesis and characterization of carbon materials as titanium dioxide carrier for removal of the selected organic pollutants from water

Abstract

The main objective of this work was to develope appropriate preparation method in order to obtain TiO2/carbon composites with the highest efficiency in removal of organic pollutants from the water. Carbon monolith and hydrothermal carbon were used as a titanium dioxide carrier for preparation of TiO2/carbon composites. Carbon monolith as a photocatalyst carrier is impregnated with particles of titanium dioxide using two methods: dip-coating method, which involves the use of a binder, and thermal treatment method. Composite photocatalysts with hydrothermal carbon as TiO2 carrier were synthesized by hydrothermal carbonization, using glucose and titanium isopropoxide, as precusors of carbon and titania, respectively...

Cilj ove doktorske disertacije je razvoj metode za dobijanje efikasnih kompozitnih fotokatalizatora, sa karbon monolitom i hidrotermalnim ugljenikom kao nosačem titan-dioksida za uklanjanje organskih zagaĎujućih materija iz vode. Karbon monolit kao nosač fotokatalizatora impregnisan je česticama titan-dioksida primenom dve različite metode: metoda potapanja (eng. dip-coating), koja podrazumeva upotrebu vezivnog sredstva, i metoda bazirana na termičkom tretmanu karbon monolita nakon uranjanja u koncentrovani rastvor TiCl4 (eng. thermal treatment)...
