Sinteza i karakterizacija ugljeničnih materijala kao nosača titan-dioksida za uklanjanje odabranih organskih zagađujućih materijala iz vode

Abstract

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)...

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...
