Electrocatalytic and surface enhanced Raman scattering (SERS) activity were investigated at palladium nanostructures electrodeposited on Au surfaces. Scanning electron microscopic and transmission electron microscope images show that the Pd nanostructures contain unique triangular rod shape. Triangular rod Pd structures exhibit highly electrocatalytic activity for oxygen reduction reaction (ORR) and methanol oxidation. Cathodic peak potential for ORR on triangular Pd is observed at ~200 mV more positive potential than that on the bare Pd surfaces. It was similar to bare Pt electrode. The anodic peak current for methanol oxidation is greater than bare Pd electrode. Moreover, triangular rod Pd provided efficient SERS activities. The SERS enhancement factor was estimated to be greater than 1600. The unique morphology and surface orientation of triangular Pd demonstrate high electrocatalytic activities and efficient SERS activities.
