Manganese substituted hexaaluminate has been prepared using the environmentally benign surfactants such as Triton X-100, under ambient condition with a commercial alumina sol and metal acetate precursors. The surface area of the pure alumina can be controlled to 10 ~ 70 m2g-1 using cetyltrimethylammonium chloride after heating in oxygen flow at 1200 C for 6 h. The crystal structure of the obtained alumina was high purity gamma-Al2O3. Incorporation of La and Mn leads to the formation of the high purity manganese substituted hexaaluminate with a surface area of 30 ~ 40 m2g-1 which is also controllable using organic additives such as urea. The catalytic activity of the manganese substituted hexaaluminate was comparable to the sol-gel derived hexaaluminate catalyst from metal alkoxides. |
