Synthesis and Characterization of PdAgNi/C Trimetallic Nanoparticles for Ethanol Electrooxidation

The direct use of ethanol in fuel cells presents unprecedented economic, technical, and environmental opportunities energy conversion. However, complex challenges need to be resolved. For instance, oxidation reaction (EOR) requires breaking the rigid C–C bond results generation poisoning carbonaceous species. Therefore, new designs catalyst electrode are necessary. In this work, two trimetallic PdxAgyNiz/C samples prepared using a facile borohydride reduction route. catalysts characterized by X-ray diffraction (XRD), Energy-Dispersive spectroscopy (EDX), photoelectron Spectroscopy (XPS), Transmission Electron Microscopy (TEM) evaluated for EOR through cyclic voltammetry (CV), chronoamperometry (CA), electrochemical impedance (EIS). XRD patterns have shown weak alloying potential between Pd, Ag co-reduction technique. generally enhanced performance compared previously reported ones, suggesting that applied synthesis may suitable mass production. Moreover, addition Ni has improved Pd physiochemical properties electrocatalytic towards reducing cell fabrication costs. containing less PdAgNi/C is higher performing presenting 2.7 A/mgPd current peak. Pd4Ag2Ni1/C terms its steady-state density active surface area.
