Abstract

A new electrocatalytic system comprising of aqueous polyoxometalates and nanoporous gold has been investigated for CO electrooxidation in acidic media using a nanoporous microelectrode technique. It is very encouragingly found that aqueous polyoxometalates at trace levels within 10-5-to-10-3 M can substantially promote the CO electrooxidation on the nanoporous gold presumably due to weak adsorption of polyoxometalates onto the nanoporous gold. This fact is important for developing highly efficient electrocatalysts for the CO electrooxidation for their applications in fuel cells, electrochemical sensors and electrochemical processes.
