摘      要：The catalytic efficacy of copper-based catalysts for volatile organic compounds（VOCs） oxidation is significantly affected by the metal oxide support s chemical properties. However, rigorous comparative analyses on TiO2and CeO2supports are scarce. This study systematically constructs Cu/TiO2and Cu/CeO2catalysts and investigates their mechanisms in promoting propane oxidation. Cu/CeO2exhibits superior performance and stability. Our research reveals the key role of Cu-O-Ce interfacial architecture in forming Cu1+sites for efficient propane adsorption and triggering surface Olattgeneration, accelerating propane combustion. These findings elucidate Cu/CeO2catalyst enhanced performance and offer insights into non-noble metal catalysts. By demonstrating CeO2catalyst superiority, this study provides a basis for selecting optimal support materials to optimize catalyst performance, driving the development of cost-effective and eco-friendly catalytic technologies for air pollution control.
