Effect of Pd on the Electrocatalytic Activity of Pt towards Oxidation of Ethanol in Alkaline Solutions
نویسندگان
چکیده
The understanding of electrocatalytic activity and poisoning resistance properties Pt Pd nanoparticles, recognized as the best electrocatalysts for ethanol oxidation reaction, is an essential step commercialization direct fuel cells (DEFCs). In this paper, mono bimetallic nanoparticles with different atomic ratios have been synthesized to study their reaction in alkaline solutions. were physiochemically characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), diffraction (XRD), photoelectron (XPS). electrochemical characterization was performed cyclic voltammetry chronoamperometry measurements. measurements indicate that much higher than nanoparticles. studies PtPd showed a significant impact composition on oxidation. Thus, highest obtained Pt3Pd2 Moreover, demonstrates catalyst surface through related prevalence acetaldehyde–acetate route polymerization acetaldehyde aldol condensation media.
