| Abstract
| - The preparation of a catalyst bed with a high surface area through an innovative method ofloading γ-alumina on a substrate prior to hydrolysis of the alumina during the process ofpreparing an alumina sol is presented. This method produces a BET surface area of 20.5 m2/g,as compared to the 13.5 m2/g achieved by conventional coating techniques, and accounts for50% additional surface area on the substrate and reduced waste of alumina in the washed awaysol. MoO3/Cu-based one-way auto-exhaust catalyst systems were studied using this catalyst bed,which might find potential use as environmental catalysts in pollution control as an economicalsubstitute for noble-metal-based catalysts.
