| 摘 要： | 用浸渍法制备了一系列含镍的催化剂，以ＴＰＲ、ＴＰＤ、ＸＲＤ及ＸＰＳ等手段分别对Ｎｉ／海泡石及Ｎｉ／Ｓｍ海泡石催化剂进行了表征。结果表明，助剂钐的加入不仅使镍粒变小，而且也降低了镍原子结合能，除此以外，镍的分散亦有提高。ＴＰＲ与ＴＰＤ测试表明钐的加入亦能引起峰温的变化。

| Abstract: | Ni/sepiolite and Ni-Sm/sepiolite catalysts were prepared by impregnation and their properties were characterized by the means of TPR, TPD, XRD and XPS, respectively. The results show that the addition of Sm to the Ni/sepiolite can decrease not only the partical size of nickel but also nickel atomic binding energy. Besides, it also increases the dispersion of nickel on sepiolite support. The reduction and desorption peak temperature in TPR or TPD curves changed after adding Sm. |
