The spatial structure regulation of catalysts could optimize the reaction pathway and enhance the mass transfer kinetics, which might realize the efficient and low-consumption removal of pollutants in Fenton-like technology. In this study, N,N-dimethylformamide (DMF) intercalation was used to adjust the interlayer spacing of FeOCl from 7.90 to 11.84 Å by a simple and rapid intercalation method, thereby enhancing the mass transfer kinetics and altering the catalytic pathway. The removal rate of BPA in the DMF-FeOCl/PS system increased by 8.78 times, showing good resistance to complex water environments (such as pH, humic acid, and anions), especially in 5 g/L high-salt wastewater. The direct electron transfer processes between Fe(IV) and pollutants mediated by interlayer Fe sites generate phenoxy radicals, and the polymerization processes occur, achieving efficient removal of pollutants and low CO₂ emissions. This study provides new insight into the efficient and low-carbon treatment of high-salt wastewater.

调节层间限制 FeOCl 以加速污染物的聚合以减少水净化中的碳排放

催化剂的空间结构调控可以优化反应途径并增强传质动力学，这可能实现类芬顿技术中污染物的高效低耗去除。在本研究中，N , N-二甲基甲酰胺 (DMF) 插层用于通过简单快速的插层方法将 FeOCl 的层间距从 7.90 调整到 11.84 Å，从而增强传质动力学并改变催化途径。DMF-FeOCl/PS体系对BPA的去除率提高了8.78倍，表现出对复杂水环境（如pH、腐殖酸、阴离子）的良好耐受性，尤其是在5 g/L的高盐废水中。层间Fe位介导的Fe(IV)与污染物之间的直接电子转移过程产生苯氧基，并发生聚合过程，实现了污染物的高效去除和低CO ₂排放。该研究为高盐废水的高效低碳处理提供了新的思路。
