摘要: 以碳钢在1.5 mol/L草酸 + 5.0 × 10−4 mol/L草酸锌溶液中浸泡90 min后形成的草酸盐转化膜为前驱体，经空气中350℃热处理2 h，在碳钢表面制备出Zn掺杂的Fe2O3纳米线氧化膜。采用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和光电流测试对氧化膜进行了表征。结果表明：Fe2O3纳米线的直径约100 nm左右。在2.5 mol/L NaOH溶液中，氧化膜在可见光照射和零偏置电压下，显示n型半导体特征的阳极光电流。Zn掺杂的Fe2O3纳米线氧化膜具有良好的光电化学性能。
Abstract: Films of Zn-doped Fe2O3 Nanowires were prepared on the surface of carbon steel using a method of thermal decomposition of oxalate conversion coatings at 350˚C in air. The coating precursors were obtained by immersing the steels in ethanol solutions of 1.5 mol/L oxalic acid with 5.0 × 10−4 mol/L zinc oxalate for 90 min. The oxide films were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and photocurrent measurement. The results indicate the Fe2O3 nanowires with diameter of ~100 nm. In 2.5 mol/L NaOH solution, the oxide films generated anodic photocurrents of n-type semiconductor behavior under visible light irradiation and zero bias. The Zn doped film generated larger photocurrent than the undoped film did.
