摘要
应用XPS方法研究了CuOCeO2/Al2O3催化剂的表面特征,探索了CeO2对CuO催化剂的助催化作用.结果表明,CeO2是较好的助催化组分,在CuO催化剂中添加适量的CeO2,可促进催化剂表面Cu+含量的增加,从而有利于CO氧化催化活性的提高.
The surface characterization of impregnated Cu Ce O/Al 2O 3 catalysts was investigated by the method of X ray photoelectron spectroscopy. The cerium oxides was a better promoter for catalysts of CuO/Al 2O 3 at the appropriate loading. The presence of CeO 2 increased the Cu + content on the surface of catalysts. So the activity of catalysts for carbon monoxideoxidation can be increased.
