Abstract
A method for preparing a catalyst includes preparing a first solution including a gold precursor and a palladium precursor, preparing an alumina suspension, heating the alumina suspension to a preferred temperature range, introducing the first solution to the alumina suspension and coincidently maintaining the pH of a resulting solution at a preferred pH level, separating solids in the resulting solution, and calcining the separated solids to form a catalyst including gold and palladium co-deposited onto alumina.
