摘要: 以聚乙烯吡咯烷酮(PVP)为添加剂，在304不锈钢基底上，从硫酸锌–氯化铵体系中用0.03 A·cm−2恒电流阴极沉积得到条纹状的金属Zn膜，经350℃ 1 h，450℃ 2 h两步热氧化得到具有大量微/纳米针的条纹ZnO薄膜。通过XRD、SEM分析了金属Zn薄膜氧化前后的结构和表面形貌，初步讨论了条纹状金属Zn膜形成机理。具有微/纳米针形貌的条纹ZnO薄膜显示出较高的光催化降解罗丹明B的性能。
Abstract: In presence of polyvinyl pyrrolidone (PVP), the stripe morphology of Zn films were galvanostatically deposited on 304 stainless steel sheets at 0.03 A·cm−2 in zinc sulfate-ammonium chloride solution. The stripe ZnO films with a lot of micro/nano needles were obtained by thermal oxidation of the stripe Zn films at 350℃ for 1 h and 450℃ for 2 h in air. The structures and morphologies of Zn and ZnO films were studied by X-ray diffraction (XRD) and Scanning electron microscope (SEM). The mechanism of formation stripe morphology Zn films was discussed preliminarily. The results of photocatalytic tests reveal that the stripe ZnO films with micro/nano needles show higher activities for degradation of rhodamine B (RhB).
