Alumina nanoparticles carrier was prepared by supersolubilizing self-assembly micelles. BET and mercury injection method were used to characterize the carrier and the influence of adhesive amount and template amount on pore character of nanometer alumina was researched. The results indicate that, when the amount of adhesive increased, surface area and bulk density increased, pore volume and pore size decreased. When the amount of template increased, pore volume and pore size increased, bulk density decreased. When template amount is greater 10 than benchmark, the surface area is 411.4 m²/g, surface area achieved maximum,less or more then this value, surface area would decrease.
