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.
