| 摘 要： | 利用拉曼光谱表征了不同方法添加ＣｅＯ２－ＺｒＯ２混合氧化物对Ｐｔ／Ａｌ２Ｏ３催化剂的影响，并采用了ＸＲＤ，Ｈ２化学吸附，ＢＥＴ表征了相应的分散度影响。结果表明：Ｃｅ、Ｚｒ、与金属Ｐｔ存在着强的相互作用，而ＣｅＯ２－ＺｒＯ２以盐的形式加入时，高度分散在Ａｌ２Ｏ３载体上，提高贵金属Ｐｔ的分散度，进而提高了反应的活性。

| Abstract: | The performance of Pt/Al 2O 3 catalysts with C eO 2-ZrO 2 in difference ways was studied by NIR-FT-Raman,BET,H 2 chemisor ption,XRD.It shows that the dispersion of Pt on Al 2O 3 is improved with the i ncreasing of dispersion of CeO 2-ZrO 2 on the surface of Al 2O 3,owing to t he strong interacting between CeO 2-ZrO 2 and Pt.And adding with salts is pr iority. |
