Abstract Nanofibers of palladium(Pd)/polyaniline(PANI) were synthesized via liquid phase chemical oxidation in dark conditions with aniline as monomer, palladium chloride (PdCl2) as palladium precursor and ammonium persulfate as oxidant. The synthesized nanofibers were characterized by XRD, FESEM, TEM, SAED, HRTEM, FT-IR spectroscopy and UV-visible spectroscopy. Electrochemical performance of ethanol oxidation was also investigated on a glassy carbon electrode modified with Pd/PANI nanofibers. The results show that the length of Pd/PANI nanofibers can reach up to 500 nm with average diameters of 20 nm. Pd nanoparticles with the average diameter of 6 nm can uniformly distribute over the PANI fibers. The electrochemical active surface area (ECSA) of the Pd/PANI/GCE (54.76 m2/gPd) is nine times higher than that of commercial Pd/C catalyst (6.08 m2/gPd). The value of jf/jb of Pd/PANI/GCE is 1.192.
