摘要
用浸渍法将Ni负载到经功能化的多壁碳纳米管上(MWCNTs)上,采用电镜(TEM)红外光谱(IR)TPR、TPD、CS2中毒实验对催化剂进行表征,以苯加氢为探针反应,结果发现经Ni修饰的多壁碳纳米管相比同样负载量的-γAl2O3载体具有更好的催化活性和抗毒性能。并且在经Ni修饰的多壁碳纳米管上容易产生“氢溢流”现象。
Nickel was successfully supported on the functionalized MWCNTs by impregnation method,The catalyst was characterized by TEM. IR.TPR. TPD. Sulfur-tolerance testing. It was found that, throught hydrogenation of benzene, Ni/CNTs had better catalytic activity and better sulfur resitance compare to Ni/γ-Al2O3. Also, MWCNTs decorated via nickel can produce ＂hydrogen spilover＂.
