| 摘 要： | 采用阳极氧化铝(AAO)模板法电化学沉积制备了Pt纳米线阵列(Pt NWs)氧还原催化剂, 通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)和电化学测试对Pt纳米线阵列催化剂的形貌和电催化性能进行了表征. 循环伏安法(CV)研究表明Pt纳米线阵列催化剂的电化学活性面积大于其几何面积; 旋转圆盘电极(RDE)测试研究发现, 制备的Pt纳米线阵列催化剂的氧还原反应(ORR)曲线的半波电势相对Pt/C的有正移, 并且Pt纳米线阵列催化剂的极限扩散电流比Pt/C大.

| Abstract: | 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 geom... |
