摘要
日益严重的水污染和气候变化导致水资源短缺。这些因素影响着环境生物多样性的丧失,并威胁着人类健康。来自工业的有毒染料颜料是一个重要的污染源。本文介绍了可能影响水中染料分解程度的 CuO-ZnO 纳米复合材料的合成方法、特性和光催化性能。利用物理气相沉积和热氧化方法制备了由氧化铜纳米线和氧化锌纳米结构组成的纳米复合材料(CuO-ZnO 纳米复合材料)。利用 X 射线衍射分析、高分辨率透射电子显微镜、场发射扫描电子显微镜、能量色散 X 射线分析和紫外可见光谱等多种技术研究了所得样品的晶体结构、表面形貌、元素组成和光学性质。通过测试亚甲基蓝在可见光照射下的降解情况,测量了纳米复合材料的光催化活性。与纯 CuO 和 ZnO 相比,纳米复合材料的光催化活性有所提高。在 120 分钟内,CuO-ZnO 纳米复合材料的染料降解率高达 94%。
CuO-ZnO nanocomposite for photocatalytic application
The rising levels of water pollution and climate change contribute to water shortages. These factors influence the loss of the environment’s biodiversity and threaten human health. Toxic dye pigments from industries are a significant source of pollution. In this article, we present the synthesis method, characteristics, and photocatalytic properties of the CuO-ZnO nanocomposite, which may affect the degree of decomposition of dyes found in water. The nanocomposite consisting of copper oxide nanowires with zinc oxide nanostructures (CuO-ZnO nanocomposite) was prepared by physical vapor deposition and thermal oxidation methods. The crystalline structure, surface topographies and morphologies, elemental composition, and optical properties of the obtained samples were studied with various techniques such as x-ray diffraction analysis, high-resolution transmission electron microscopy, field emission scanning electron microscopy, energy dispersive x-ray analysis, and UV-vis spectroscopy. The photocatalytic activity of the nanocomposite was measured by testing the degradation of methylene blue under visible irradiation. An increase in the photocatalytic activity of the nanocomposite was observed compared to pure CuO and ZnO. The CuO-ZnO nanocomposite demonstrated a high dye degradation of about 94% during 120 min.
