Here, the transient reduction of NO with CO and naphthalene in the presence of oxygen was studied on a Ca/Cu/YCeO2-TiO2catalyst. Response surface methodology was used to identify the optimum amounts of calcium, copper, and cerium. The optimized Ca/Cu/YCeO2-TiO2catalyst was then extensively studied and characterized. The coupling of yttrium-stabilized ceria with TiO2provided an active support that effectively activated naphthalene. When calcium and copper were added to the support, the obtained Ca/Cu/YCeO2-TiO2catalyst achieved the full conversion of CO and naphthalene and 72% conversion of NO. The Ca/Cu/YCeO2-TiO2catalyst possessed labile oxygen species, which might be related to the high catalytic activity. © The Royal Society of Chemistry 2021.enCalciumCalcium compoundsCatalyst activityCopper; NaphthaleneOxygenReductionTitanium compoundsArtículoAttribution-NonCommercial 3.0 Unported (CC BY-NC 3.0)10.1039/d1ra08412g
