英文摘要	Platinum nanowire arrays (Pt NWs) catalyst was fabricated by electrodepositing with anodic aluminum oxide (AAO) as a template. The morphology and oxygen reduction reaction (ORR) electrocatalytic properties of the as-prepared platinum nanowire array catalysts were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electrochemical measurements. The cyclic voltammetry (CV) showed that the specific electrochemical surface area (ECSA) of the Pt NWs was much higher than the geometric area. The half wave potential in the oxygen reduction reaction curves of the Pt NWs was more positive than that of Pt/C from the rotating disk electrode (RDE) measurements. Moreover, Pt NWs catalysts give higher limiting diffusion current by comparison with that of conventional Pt/C catalyst.
