  • Electrodes having Pt nanoparticles on RuOnanoskins
    Patent number: 10651478
    Abstract: An article having a titanium, titanium carbide, titanium nitride, tantalum, aluminum, silicon, or stainless steel substrate, a RuO2 coating on a portion of the substrate; and a plurality of platinum nanoparticles on the RuO2 coating. The RuO2 coating contains nanoparticles of RuO2. A method of: immersing the substrate in a solution of RuO4 and a nonpolar solvent at a temperature that is below the temperature at which RuO4 decomposes to RuO2 in the nonpolar solvent in the presence of the article; warming the article and solution to ambient temperature under ambient conditions to cause the formation of a RuO2 coating on a portion of the article; and electrodepositing platinum nanoparticles on the RuO2 coating.
