  • Electrolytic bath compositions and method for electrodeposition of amorphous chromium
    Patent number: 4690735
    Abstract: An electroplating bath for depositing amorphous chromium material comprising organic additives and a chromium trioxide to sulfuric acid weight ratio of from about 2:1 to about 40:1.
    Type: Grant
    Filed: February 4, 1986
    Date of Patent: September 1, 1987
    Assignee: University of Florida
    Inventors: Herbert A. Laitinen, Shigeo Hoshino
  • Process for preparing a platinum surface on tin oxide substrate
    Patent number: 4552641
    Abstract: A process for coating tin oxide with platinum which comprises soaking a tin oxide substrate in a strong caustic solution to activate the substrate, washing the substrate to remove all caustic solution, immersing the washed substrate in an alkaline solution containing Pt(OH).sub.6.sup..dbd. ions applying an electric potential of +0.1 to +0.7 volt to the immersed substrate, and recovering the substrate having a coating of platinum. This process is useful in preparing active platinum-coated catalysts using very small amounts of platinum.
    Type: Grant
