Abstract

This invention relates to a process for depositing one or more catalytically reactive metals on a carrier, said process comprising selecting a carrier and depositing a catalytically effective amount of one or more catalytically reactive metals on the carrier, the deposition effected by submersing the carrier in an impregnation solution wherein the hydrogen ion activity of the impregnation solution has been lowered. The invention further relates to catalysts made from the process.
