The removal of typical atmospheric pollutants, such as nitrogen oxide (NO) and toluene (PhCH3), has significant importance for environmental protection. In this study, CeO2-MoO3/TiO2 catalyst was prepared by the impregnation method, excellent simultaneous performance NO PhCH3 investigated. temperature range 300-400ºC, efficiency denitration all exceeded 90%, maximum 94.16% reached at 275ºC, while 99.52% 350ºC. Furthermore, through various characterization techniques combined with density functional theory (DFT) calculations, mechanism MoO3 promoting possible reaction processes reactants were explored. results showed that introduced provided abundant acid sites catalyst, adsorption strength over surface significantly enhanced compared CeO2/TiO2 counterpart, thereby facilitating further activation surface. Additionally, more oxygen vacancies chemisorbed species appeared after introduction MoO3, redox cycle between Ce4+ Ce3+ well migration active also much facile, which made own ability. This study can provide a theoretical basis development catalysts suitable complex flue gas conditions containing PhCH3.
