摘要 本文以CO氧化模式反应考察CuO/γ-Al2O3、CuO/CeO2/γ-Al2O3、CuO/α-Al2O3和CuO/CeO2/α-Al2O3催化剂的氧化活性.运用TPR技术研究了催化剂的还原性能。结果表明:CeO2能提高Al2O3负载CuO催化剂的CO氧化活性,抑制CuAl2O4尖晶石的形成,改善催化剂的热稳定性。 The oxidation activity of CuO/γ-Al2O3, CuO-CeO2/γ-Al2O3,CuO/α-Al2O3, and CuO-CeO2/ α-Al2O3 catalysts was investigated by the oxidation of carbon monoxide as a model reaction. The reducibility of the catalysts was studied by TPR techniques. CeO2 can promotes the activity and the stability of CuO/γ-Al2O3, and CuO/α-Al2O3, catalysts, and inhibits the formation of CuAl2O4 .
