Abstract

Catalytic electrode layers with metal nanoparticles attached to the surfaces of carbon nanotubes are used in a membrane electrode assembly and an electrochemical sensor. Metal nanoparticles are readily transferred onto a polyelectrolyte membrane at room temperature, and the transfer is highly reliable. For attachment of metal nanoparticles onto the surfaces of carbon nanotubes, the carbon nanotubes are activated, and a metallic precursor and a reducing agent are introduced onto the activated surfaces. Through this process, the metal is reduced and the metal nanoparticles are formed on the surfaces of the carbon nanotubes.
