The large consumption and discharge of antibiotic ciprofloxacin (CIP) force us to find an effective technology to removal of CIP. Herein, three dimensional (3D) tripyramid TiO₂ architectures were eco-friendliness and facile synthesized with the assistance of aloe extracts and hydrothermal method and then were used in the photocatalytic removal of CIP pollutants. It’s found that residual biologically active components on the surface of TiO₂ induced to the formation of 3D tripyramid architectures. The optimized composite showed a removal efficiency of 90% within 60 min. Compared to rod-like TiO₂, 3D tripyramid TiO₂ architectures displayed 3.4 times for photocatalytic degradation of CIP under UV–vis light irradiation. The present investigation initiates a green and eco-friendliness path for the construction of high-performance hierarchical catalysts in the application of wastewater purification.

抗生素环丙沙星（CIP）的大量消耗和排放迫使我们寻找一种有效的技术来去除CIP。在这里，三维（3D）三棱锥TiO ₂结构是生态友好的，并且在芦荟提取物和水热法的帮助下易于合成，然后用于光催化去除CIP污染物。已经发现，TiO ₂表面上残留的生物活性成分诱导了3D三棱锥结构的形成。优化的复合材料在60分钟内的去除效率为90％。与棒状TiO ₂相比，3D三棱锥TiO ₂在紫外线可见光照射下，CIP架构对CIP的光催化降解显示了3.4倍。本研究为废水净化应用中高性能分级催化剂的构建开辟了一条绿色环保的道路。
