Oxidative Decomposition of TCE over TiO 2 -Supported Metal Oxide Catalysts

Oxidative TCE decomposition over -supported single and complex metal oxide catalysts has been conducted using a continuous flow type fixed-bed reactor system. Different types of commercial were used for obtaining the supported catalysts via an incipient wetness technique. Among a variety of titanias and metal oxides used, a DT51D would be the respective promising support and active ingredient for the oxidative TCE decomposition. The catalyst gave a significant dependence of the catalytic activity in TCE oxidation reaction on the metal loadings. The use of high contents for preparing catalysts might produce crystallites on the surface of , thereby decreasing catalytic performance in the oxidative decomposition at low reaction temperatures. Supported -based bimetallic oxide systems offered a very useful approach to lower the amounts without any loss in their catalytic activity for the catalytic TCE oxidation and to minimize the formation of Cl-containing organic products in the course of the catalytic reaction.
