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.
