摘要

Preparing a bimetallic catalyst on a support made of gold and one or more other metals, comprises depositing the gold and various metals on support by anion exchange by contacting one or more aqueous solutions containing one or more chlorinated water-soluble gold salts and/or one or more chlorinated water-soluble metal salts other than gold salts, with the support, at a pH = to the isoelectric point of the support.
