Nickel nanowires decorated with ultra-low palladium loading as an effective electrocatalyst for NaBH4 oxidation†
Abstract
Binder-free Pd decorated Ni nanowire (Pd/Ni NW) electrodes are simply fabricated by template-assisted electrodeposition of nickel nanowires and subsequently by spontaneous growth of palladium electrocatalysts on the nickel nanowire surface. The Pd/Ni NW electrode presents superior electrochemical activity and desirable stability towards NaBH4 electrooxidation in an alkaline environment.
