The present work reports on the fabrication of high-density polyethylene sponges, decorated with Mn-doped ZnO nanostructures. The sponges were developed utilizing three-dimensional printing technology, while Mn-doped ZnO nanostructures, with varying doping levels, were grown at mild temperatures. The nanostructures were fully characterized by means of scanning electron microscopy, X-ray diffraction, and Raman spectroscopy, revealing the existence of Mn doping. Moreover, their photocatalytic properties were investigated using the degradation/decolorization of a commercially available liquid laundry detergent, based on synthetic, less foaming ingredients, under UV irradiation. The Mn-doped ZnO nanostructures show better photocatalytic activity at higher doping levels. This study demonstrates that it is possible to achieve the adequate degradation of a typical detergent solution in water by means of low-cost and environmentally friendly approaches, while Mn-doped ZnO/HDPE nanostructures are good candidates for real environmental applications.
本工作报道了用锰掺杂的ZnO纳米结构修饰的高密度聚乙烯海绵的制备。这些海绵利用三维打印技术制成，同时在温和温度下生长出具有不同掺杂水平的锰掺杂ZnO纳米结构。通过扫描电子显微镜、X射线衍射和拉曼光谱对纳米结构进行了全面表征，揭示了锰掺杂的存在。此外，在紫外线照射下，基于合成的、低泡成分的市售液体洗衣液的降解/脱色，研究了它们的光催化性能。锰掺杂的ZnO纳米结构在较高掺杂水平下表现出更好的光催化活性。这项研究表明，通过低成本和环境友好的方法可以实现水中典型洗涤剂溶液的充分降解，而锰掺杂的ZnO/HDPE纳米结构是实际环境应用的良好候选材料。
