Efficient catalytic activity of NiO and CeO₂ films in benzoic acid removal using ozone.

ABSTRACT: This research focuses on the synthesis of NiO and CeO₂ thin films using spray pyrolysis for the removal of benzoic acid using ozone as an oxidant. The results indicate that the addition of CeO₂ films significantly enhances the mineralization of benzoic acid, achieving a rate of over 80% as the CeO₂ films react with ozone to produce strong oxidant species, such as hydroxyl radicals, superoxide radicals, and singlet oxygen as demonstrated by the presence of quenchers in the reaction system. The difference in catalytic activity between NiO and CeO₂ films was analyzed via XPS technique; specifically, hydroxyl oxygen groups in the CeO₂ film were greater in number than those in the NiO film, thus benefitting catalytic oxidation as the
