Abstract


  • Palladium-Nickel (Pd-Ni) hollow nanoparticles were synthesized via a modified galvanic

    replacement method using Ni nanoparticles as sacrificial templates in an aqueous medium. X-ray

    diffraction and transmission electron microscopy show that the as-synthesized nanoparticles are

    alloyed nanostructures and have hollow interiors with an average particle size of 30 nm and shell

    thickness of 5 nm. Compared with the commercially available Pt/C or Pd/C catalysts, the

    synthesized PdNi/C has superior electrocatalytic performance towards the oxygen reduction

    reaction, which makes it a promising electrocatalyst for alkaline anion exchange membrane fuel

    cells and alkali-based air-batteries. The electrocatalyst is finally examined in an H2/O2 alkaline

    anion exchange membrane fuel cell; the results show that such electrocatalysts could work in a

    real fuel cell application as a more efficient catalyst than state-of-the-art commercially available

    Pt/C.
