| Abstract: | Pd nanowire arrays were prepared by electro-deposition method using anodic aluminum oxide(AAO) template, and Pt nanoparticles were deposited on the Pd nanowire array to prepare Pd nanowires/Pt nanoparticles (PdNWs/PtNPs) composite electrode. The morphology of PdNWs/PtNPs was observed using scanning electron microscope (SEM), and the component of PdNWs/PtNPs was collected in an energy dispersive spectrometer (EDS). The electro catalytic activity in oxygen reduction at PdNWs/PtNPs composite was measured by cyclic voltammetry(CV) and linear sweep voltammetry (LSV). The results revealed that PdNWs/PtNPs composite exhibits better electro catalytic activity in oxygen reduction than pure PdNWs or PtNPs, in which, the peak oxygen reduction current of PdNWs/PtNPs is 8.1 times higher than that of pure PtNPs, and 2.1 times higher than that of pure PdNWs respectively. Moreover, the reduction potential positively shifts 140mV in PdNWs/PtNPs. |
