摘要： 采用原位合成法和传统浸渍法以价格低廉的硝酸铝作为铝源, 聚乙二醇1540为模板剂, 硝酸镍为镍源, 制备出负载Ni金属有序介孔氧化铝催化剂, 并采用BET、TEM、XRD、TG多种测试技术对合成催化剂的物理化学性质和结构特征进行了表征. 实验结果表明, 两种方法均能制备出比表面积大(＞210 m2·g-1)、孔径分布窄(4 nm左右)的负载Ni金属介孔氧化铝催化剂. 与浸渍法相比, 原位合成法所制备的负载Ni金属有序介孔氧化铝镍离子与载体具有更强的相互作用力, 且孔结构具有一定的有序性.

Abstract: Ni catalysts supported on mesoporous alumina (Ni-Al2O3) were prepared by in-situ synthesis method and traditional impregnation method. The physical, chemical, and structure properties of synthesized catalysts were investigated by several measuring technologies (BET, TEM, XRD, TG). The experimental results showed that Ni-Al2O3 with high surface area(＞210 m2·g-1) and narrow pore size distribution(4 nm) could be synthesized by both in-situ synthesis method and impregnation method. In contrast to the impregnation method, the interaction between nickel ion and the carrier was stronger in Ni-Al2O3 synthesized by in-situ synthesis method, and the structure of pore showed to be organized in some degree.
