近日，印度SRM科学技术研究所Bernaurdshaw Neppolian团队报道了从实验室到工业应用：广谱S型光催化剂实现连续流声光催化降解持久性污染物。相关论文发表在2025年12月15日出版的《结构化学》杂志上。

工业化的快速推进导致有害化学物质被大量排放到环境中，这一严峻形势促使科学界重新审视传统废水处理技术。声光催化作为一种协同作用的绿色技术，通过结合超声波与可见光的双重能量，已发展为环境修复领域备受关注的前沿方向。沸石咪唑酯骨架（ZIF-67）作为金属有机框架材料的一种，凭借其极高的比表面积、丰富孔隙结构及配位灵活性，成为催化剂设计的理想载体。

研究组以ZIF-67为基体，成功构建了钨酸钴修饰的ZIF-67杂化纳米复合材料作为声光催化剂核心，并在双能量场照射下实现了对四环素的高效降解。该CoWO₄/ZIF-67催化剂在75分钟内达到98%的四环素降解率，其性能显著优于单一的声催化或光催化处理，且展现出优异的可重复使用性。机理研究表明，催化剂的结构特性与物理化学性质同能量诱导产生的活性氧物种之间存在强关联，这一发现得到了理论计算的印证。研究进一步设计制造了20升规模连续流声光催化反应器，用于评估所合成催化剂在含干扰离子的实际废水样本中的处理效能。该系统实现了总有机碳含量85%的去除率，展现出卓越的规模化应用潜力与实际可行性，为高效环保处理新兴有机污染物提供了创新路径。

Abstract: The rapid pace of industrialization has resulted in the alarming discharge of detrimental chemicals into the environment, prompting the scientific community to rethink conventional wastewater treatment technologies. Sonophotocatalysis, a synergistic green approach, harnessing the combined forces of ultrasound and visible light, has emerged as a promising frontier in environmental remediation. Leveraging the exceptional surface area, porosity, and coordination flexibility of Zeolitic Imidazole Frameworks (ZIF-67), a type of Metal-organic framework (MOF), makes it an excellent scaffold for catalyst design. Forming the core of this approach, a CoWO4-decorated ZIF-67 hybrid nanocomposite was developed and utilized as a sonophotocatalyst to degrade tetracycline (TC) under dual-energy exposure. The CoWO4/ZIF-67 catalyst achieved an unprecedented TC degradation efficiency of 98% within 75 minutes, outperforming standalone sonocatalytic and photocatalytic treatment, with excellent reusability. Mechanistic insights, supported by theoretical studies, revealed a strong interaction between the structural and physicochemical properties of the catalyst and energy-induced reactive oxygen species (ROS) generation. A large-scale continuous-flow sonophotocatalytic reactor of 20 L was fabricated to evaluate the performance of the synthesized catalyst on real wastewater samples containing interfering ions. The system achieved an 85% reduction in total organic carbon (TOC), demonstrating excellent scalability and practical applicability, offering a promising approach for treating emerging organic pollutants in an efficient and environmentally friendly manner.
