Abstract: The macroporous alumina carrier as the host of catalysts were prepared by supersolubility stiu selfassembly method. The properties of carrier were characterized by BET, TEM, XRD and so on. In MoNiP solution, macroporous hostguest catalyst was prepared using the positive micelle as template. The effect of different amount and type of surfactant on the formation of micelles was examined. The most appropriate amount of template was optimized. The hostguest macroporous catalytic materials were characterization by BET and electron microprobe analysis method (EMPA). The results showed that the catalytic material had pore volume of 0.38 cm3/g, specific surface area of 61~ 90 m2/g, average pore size of 9.3 ~13 nm, most probable pore diameter of 12.5 nm and 45 nm. The pore size distribution in the range of 10 ~60 nm were highly concentrated which occupied about 53%~70%. The amount of active metal was between 18% and 27%, and it evenly dispersed in the catalyst by EMPA analysis. 
