摘　　要：:用不同的载体 ( Mg O、α- Al2 O3、γ- Al2 O3和 Mg Al2 O4 )制备了 4种镍基催化剂并对它们进行了氨分解活性评价。采用 TPR技术研究了这些催化剂的还原行为及载体表面和 Ni O组分的相互作用 ,并用 XRD对催化剂的固相结构进行了表征。Nickel oxides supported on several types of carriers(MgO,α Al 2O 3,γ Al 2O 3 and MgAl 2O 4)were evaluated for the ammonia decomposition.The reduction behavior and the surface interaction between the nickel oxides and carriers were studied by TPR technique,and the solid studied by TPR technique,and the solid structures were characterized by XRD.
