Over the last few decades, the application of photocatalysis for mineralizing persistent organic pollutants and other new emerging contaminants has gained increasing research and industry attention. However, the integration of catalyst fabrication and reactor design has not yet been realized for photocatalytic water decontamination applications. Herein, we present, for the first time, a facile, scalable, and eco-friendly strategy for the direct synthesis and integration of hairy ZnO@ZnS core@shell Cu cables in a continuous flow tubular-type reactor. The hairy ZnO@ZnS core@shell Cu cables exhibited (i) excellent photocatalytic performance (photocatalytic degradation > 99%, mineralization > 99%) for continuous water decontamination of both single- (methylene blue) and multi-pollutants (methylene blue, p-nitrophenol, and rhodamine B) under artificial UV-filtered sunlight irradiation; (ii) a large surface area (90.1 m²g⁻¹) and a large number of active sites owing to the hairy architecture; (iii) enhanced light absorption in the visible region due to the ZnO@ZnS core@shell heterostructure, which promotes the separation of photogenerated carriers; (iv) improved light trapping capability due to the hairy architecture; (v) high photostability with minimal photocorrosion (<2% after 180 h of continuous irradiation); and (vi) excellent robustness. The recyclability and potential for direct re-fabrication of a fresh photocatalyst were also successfully confirmed. Thus, hairy ZnO@ZnS core@shell Cu cables were demonstrated to be a reliable and promising immobilized photocatalysts for the efficient mineralization of persistent organic pollutants and for the total/partial oxidation of other emerging pollutants in a continuous flow tubular-type reactor.

在过去的几十年中，光催化技术在矿化持久性有机污染物和其他新兴污染物方面的应用越来越受到研究和行业的关注。然而，对于光催化水净化应用，尚未实现催化剂制造和反应器设计的集成。在此，我们首次提出了一种简便，可扩展且环保的策略，用于在连续流管式反应器中直接合成和集成多根ZnO @ ZnS核壳金属Cu电缆。毛状ZnO @ ZnS芯壳铜电缆表现出（i）出色的光催化性能（光催化降解> 99％，矿化度> 99％），可对单个（亚甲基蓝）和多污染物（亚甲基蓝，p -硝基苯酚 和若丹明B）在人造紫外线过滤的阳光照射下；（ii）大表面积（90.1 m²克^-1）以及由于其毛茸茸的架构而导致的大量活动场所；（iii）由于ZnO @ ZnS核@壳异质结构而增强了可见光区域的光吸收，从而促进了光生载流子的分离；（iv）由于毛状结构而提高了光捕获能力；（v）高光稳定性和最小的光腐蚀（连续照射180小时后<2％）；（vi）出色的鲁棒性。还成功地证实了新鲜光催化剂的可回收性和直接再造的潜力。因此，长毛状ZnO @ ZnS核壳铜电缆被证明是一种可靠且有前途的固定化光催化剂，用于在连续流管式反应器中有效地持久化有机污染物的矿化以及其他新兴污染物的全部/部分氧化。
