Oxygen Reduction Reaction at Carbon-Based Particles Prepared by Microwave-Assisted Catalytic Decomposition Measured in Acetonitrile

Abstract

New carbon-based particles prepared using methane by microwave-assisted catalytic decomposition has been developed. The prepared carbon-based particles contained a nanographene-covered nickel, carbon nanotube, and others. In non-aqueous solvent, an oxygen reduction reaction (ORR) at the prepared carbon-based particles treated with acidic solution in advance was evaluated by using a porous microelectrode and milimeter-size diskelectrode based on electrochemical methods. The ORR was compared to commercially available glassy carbon, carbon fiber, Au, and Pt electrodes. As a result, the onset potentials for ORR at the prepared carbon-based particle were slightly better than other electrodes.
