Semiconductor oxides belonging to various families are ideal candidates for application in photocatalytic processes. One of the challenges facing photocatalytic processes today is improving their efficiency under sunlight irradiation. In this study, the growth and characterization of semiconductor oxide nanostructures and composites based on the ZnO and CuO families are proposed. The selected growth method is the resistive heating of Zn and Cu wires to produce the corresponding oxides, combined with galvanic corrosion of Zn. An exhaustive characterization of the materials obtained has been carried out using techniques based on scanning electron microscopy and optical spectroscopies. The method we have followed and the conditions used in this study present promising results, not only from a degradation efficiency point of view but also because it is a cheap, easy, and fast growth method. These characteristics are essential in order to scale the process beyond the laboratory.
属于不同族的半导体氧化物是光催化过程应用的理想候选材料。当今光催化过程面临的挑战之一是提高其在阳光照射下的效率。在本研究中，提出了基于ZnO和CuO族的半导体氧化物纳米结构及复合材料的生长与表征。所选的生长方法是对Zn和Cu丝进行电阻加热以生成相应的氧化物，并结合Zn的电偶腐蚀。已使用基于扫描电子显微镜和光谱学的技术对所得材料进行了详尽的表征。我们所采用的方法及本研究中使用的条件不仅从降解效率的角度来看呈现出有前景的结果，而且因为它是一种廉价、简便且快速的生长方法。这些特性对于将该过程扩大到实验室规模之外至关重要。
