Summary: The composite catalysts of Pd‐MoO2/C for ethanol oxidation reaction (EOR) were prepared by microwave sintering. MoO3 was thermally reduced to MoO2 by carbon black in the preparing process of the Pd‐MoO2/C material. The TEM analysis showed that Pd‐MoO2 was well polymerized. Chronoamperometric, cyclic voltammetry, and electrochemical impedance spectra methods were applied to reveal the performance for EOR at room temperature. The Pd‐MoO2/C electrode exhibited considerable high activity and stability. MoO2 as a co‐catalyst significantly improved the catalytic activity of Pd‐MoO2/C for EOR. The MoO2/C electrode does not catalyze the ethanol molecule in the alkaline medium. The Pd‐MoO2/C‐50 and Pd/C electrodes show oxidation current at around −0.6 V (vs HgO/Hg) during the forward scanning process. The Pd‐MoO2/C electrode exhibited significantly high activity and stability. Metal oxide could affect both the catalytic activity and stability. [ABSTRACT FROM AUTHOR]
