| 摘 要： | SBA-15表面经嫁接方式引入氨基官能团，与Ni络合制备了SBA-15负载的Ni催化剂(Ni/SBA-15N)。同时，采用传统的浸渍法制备了具有相似Ni负载量的催化剂(Ni/SBA-15)。在负载量相近条件下，Ni/SBA-15N的Ni颗粒分散性均高于Ni/SBA-15。XRD和TPR结果表明，催化剂焙烧后，在氨化SBA-15表面，Ni以硅酸镍形式存在，而在SBA-15表面，Ni以NiO形式存在。Ni/SBA-15对氯苯催化加氢脱氯活性不随Ni负载量的变化而变化；而在Ni/SBA-15N中，Ni负载量增加，催化剂活性增加。

| Abstract: | Mesoporous silica supported Ni catalysts were prepared using the grafting method via adsorption of Ni2+ on aminopropyl functionalized SBA-15 (denoted as Ni/SBA-15N). For comparison, supported Ni catalysts on unmodified SBA-15 were also prepared using the conventional impregnation method (denoted as Ni/SBA-15). At similar Ni loading, the Ni dispersion of Ni/SBA-15N was higher than that of Ni/SBA-15. XRD and TPR results show that nickel silicate is formed on the surface of aminopropyl functionalized SBA-15, while NiO is observed on the surface of SBA-15. For the gas phase catalytic hydrodechlorination of chlorobenzene, the Ni loading has minor effect on the catalytic activity of Ni/SBA-15, whereas increasing the Ni loading will result in the enhanced catalytic activity of Ni/SBA-15N. |
