Effect of reduction treatment: A comparative study was conducted on CeO₂ nanorod-supported CuO_x catalysts before and after reduction treatment to gain insight on the effects of the copper oxidation state and catalyst–support interfacial interactions on CO oxidation. An abundance of surface defects are found on CeO₂ nanorods from high-resolution TEM, which consequently may be critical to strong CuO_x(0≤x≤1)–CeO_2−x(0≤x≤0.5) interactions, therefore resulting in the improved low-temperature catalytic activity.

CeO2纳米棒负载的CuOx催化剂上还原处理对CO氧化的影响

还原处理的效果：在还原处理之前和之后，对CeO ₂纳米棒负载的CuO _x催化剂进行了比较研究，以了解铜氧化态和催化剂与载体之间的相互作用对CO氧化的影响。表面缺陷的丰度上的CeO发现_2个从高分辨率TEM，其因此可能是关键的，以强的CuO纳米棒_X（0≤ X ≤1）-CeO _{2- X}（0≤ X ≤0.5）的相互作用，因此导致改善的低温催化活性。
