Abstract

Ceria films (CeO_2(f)) were deposited on glass substrate by a spray pyrolysis method. The catalytic oxidation performance of CeO_2(f) was evaluated in the removal of 4-chlorophenol (4-CPh) and 4-phenolsulfonic acid (4-SPh). The catalytic oxidation reactions were carried out in water with ozone as an oxidant agent. Conventional and catalytic ozonation achieved complete removal of both compounds. Furthermore, TOC results showed higher catalytic activity with six CeO_2(f) films in comparison with conventional ozonation after 120 min for the oxidation of both 4-CPh and 4-SPh. After five consecutive reuses of CeO_2(f), the similar TOC removal for 4-CPh demonstrated the ceria films stability.
