【Abstract】 A new support, zirconia alumina spherical particles, was synthesized by means of a sol gel method. The physicochemical properties such as the acid base properties, the pore volume, the surface area and the average pore diameter of this novel support before and after acid treatment were investigated. The results show that the acid corroded zirconia alumina support is of a larger surface area and better pore structure as compared with the native zirconia alumina particles.更多还原
