The CeO₂/γ-Al₂O₃ supports were prepared and pretreated in different atmospheres to adjust the valence state of surface Ce element, then Cu(CH₃COO)₂ was impregnated as the precursor to prepare CuCeAl samples. XRD and H₂-TPR results indicate that the CeO₂/γ-Al₂O₃ support pretreated by reducing atmosphere has more active oxygen atoms, consequently has more dispersed Cu²⁺/Cu⁺ species on the surface. The "NO+CO" reaction tests reveal that the dispersed Cu²⁺/Cu⁺ are the active species for NO conversion, while crystalline Cu⁰ promotes the N₂ selectivity at low temperatures. Hence, the catalysts containing both dispersed Cu²⁺/Cu⁺ and a few crystalline Cu⁰ have the optimal catalytic efficiency.
