1. A process of depositing fine-nanoscale gold onto a nanoparticulate support medium by physical vapor deposition in an oxidizing atmosphere, the process comprising the steps of, in order:
providing a nanoparticulate support medium that is not a physically vapor deposited support medium; placing the nanoparticulate support medium in a physical vapor deposition apparatus; exposing the nanoparticulate support medium to an oxidizing atmosphere in the physical vapor deposition apparatus; and, physically vapor depositing fine-nanoscale catalytically active gold onto the nanoparticulate support medium while the nanoparticulate support medium is the oxidizing atmosphere in the physical vapor deposition apparatus. |
