Abstract

Abstract: In the present work, the performance of templated Pd‐based catalysts (TPL.Pd1 Sn x /NF) with different atomic ratio on the alkaline electrooxidation of ethanol was investigated. The superb mass activity (3246.6 mA mg −1 Pd compared with 289.9 mA mg −1 Pt for state of the art commercial Pt/C) as well as preferable long time stability, anti‐poisoning property, and conductivity of the optimum structure (TPL.Pd1 Sn20 /NF) towards electrooxidation of ethanol were proved by electrochemical experiments. The comparative study of electrocatalytic oxidation of acetaldehyde on the surface of TPL.Pd1 Sn20 /NF and TPL.Pd/NF exhibited that the presence of tin in the structure of TPL.Pd1 Sn20 /NF not only substantially promoted C1 pathway but also appreciably prevented the aldol condensation and deactivation during the electrooxidation of ethanol. Abstract : Ethanol electrooxidation catalyst : The superb ethanol oxidation reaction (EOR) activity of TPL.Pd1 Sn20 /NF as a result of synergistic effect of morphology and composition was proven. The effective role of NF as the excellent substrate was explained. The strong preference of TPL.Pd1 Sn20 /NF to TPL.Pd/NF for EOR dominant pathway was demonstrated.
