摘要: Pd/C promoted with nanocrystalline oxides electrocatalysts were prepared by the intermittent microwave heating. The electrooxidation of methanol, ethanol, glycerol and ethylene glycol on CeO2 ,C o 3O4, Mn3O4 NiO catalysts in alkaline media was studied. Such are superior to Pt-based terms activity poison tolerance. most significant result is that onset potential for ethanol oxidation Pd–NiO/C electrocatalyst shifted negatively 300 mV compared Pt/C under same experimental conditions. electrochemical parameters measured analyzed. � 2005 Elsevier B.V.
