摘　　要：采用溶胶 -凝胶法制备了负载型镍基超粒子催化剂 Ni/Al2 O3,研究表明活性组分 Ni O与载体 Al2 O3之间有较强的相互作用 ,活性组分 Ni O超细、超分散性 .有效地提高活性组分的催化活性 .该催化剂具有高的活性 。Supported Ni ultrafine partical catalysts were prepared by means of sol-gel method. The results show that the interaction between NiO and Al 2O 3 are strong. Catalytic activity of active component NiO could be effectively improved by ultrafine and super dispersion of it. These catalysts have high activity, high stability and good resistance to carbon deposition.
