Abstract:
Complete oxidation of ethanol is a pressing need for direct ethanol fuel cells (DEFCs) owning to high energy conversion. However, it holds great challenges on account of sluggish kinetics for CC bond cleavage and high susceptibility to CO poisoning. Herein, ternary PtPdCu nanocrsytals are synthesized and investigated for complete oxidation of ethanol. The obtained ternary PtPdCu nanodendrites (PtPdCu NDs) have a stepped surface, providing abundant active sites. Due to the structural and synergistic effects, ternary PtPdCu NDs exhibit a mass activity of 5.59 A mgPtPd-1 and specific activity of 15.82 mA cm-2 towards ethanol oxidation reaction, which are 6.4 and 3.6 times larger than that of commercial Pt/C. Further studies reveal that ternary PtPdCu NDs show strong abilities of CO anti-poisoning and CC bond cleavage, enhancing the C1 pathway selectivity.
