Highly Recyclable Pd@Ni Foam as Multifunctional Catalyst by Mussel-Inspired Surface Modification |
| 초록 |
In this study, nickel (Ni) foam is used as supporting material for palladium (Pd) to make recyclable multifunctional catalyst with large surface area. Pd@Ni foam catalyst was fabricated via electroless plating with surface modified Ni foam. By using adhesive polydopamine (PDA) as surface modifying agent, a simple and novel method for fabricating Pd@Ni foam composite was developed. PDA-Ni foam and Pd@Ni foam composite with a PDA intermediate layer were characterized by X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FE-SEM), and X-ray diffraction (XRD). Fabricated catalyst was employed in 4-nitrophenol (4-NPh) reduction reaction which is essential for chemical synthesis and removal of toxic aromatic pollutant. Also, ethanol oxidation for direct ethanol fuel cell (DEFC) was conducted with Pd@Ni foam electrode. |
