Effect of stabilizers on the synthesis of palladium–nickel nanoparticles supported on carbon for ethanol oxidation in alkaline medium

摘要: Abstract PdNi/C electrocatalysts for ethanol oxidation in alkaline medium are fabricated using four stabilizers, i.e., glycine (G), ethylene diamine tetraacetic acid (EDTA), sodium citrate (SC), and dodecyl sulfate (SDS) with the same reducing process reaction parameters. X-ray diffraction characterization shows PdNi nanoparticles all possess face-centered cubic structure different alloying degree. TEM results show that PdNi/C-G PdNi/C-SC have uniform dispersion ellipse morphology, while particle agglomeration occurs on PdNi/C-EDTA PdNi/C-SDS. Electrocatalytic activities of these measured by cyclic voltammetry chronoamperometry techniques. The electrocatalytic change lattice contraction. electrocatalyst exhibits best activity among electrocatalysts, which is ascribed to an appropriate
