Abstract

Low-quantity 1 wt% palladium nanoparticles grafted manganese oxide/graphene/(Pd/MnOx/GR) nanocomposite were prepared by using a cost-effective one-pot method. The Pd/MnOx/GR nanocomposite exhibited high electrocatalytic ability to oxidize ethylene glycol in alkaline medium. The Pd/MnOx/GR electrode demonstrated the highest forward anodic peak current density of 3.8 mA/cm², when compared with the modified Pd/MnOx and Pd/GR electrodes. The poisoning intermediates formed during the electrooxidation reactions were removed by changing the upper potential limit. The GR/MnOx acted as a good support to achieve maximum utilization of the Pd nanoparticles. This work could provide new insights into the simple fabrication of catalytic electrodes with high performance for alcohol fuel cell applications.
