Membrane-based persulfate catalysis technology offers a dual approach to wastewater treatment by facilitating both physical separation and chemical oxidation. This innovative method significantly enhances pollutant removal efficiency while mitigating membrane fouling, positioning it as a promising advanced oxidation technology for wastewater management. This review comprehensively examines the critical aspects of material design, activation mechanisms, and technological challenges. Membrane materials and structures are crucial for enhancing the overall efficiency of the technology. By analyzing various catalytic materials and modification strategies, the study reveals the intricate interactions between membrane structures, catalytic performance, and pollutant degradation. The clear mechanism of pollutant degradation is the key to achieve accurate degradation. The research highlights three primary activation pathways: free radical, non-radical, and hybrid mechanisms, each offering unique advantages in addressing complex water contamination. Finally, the future challenges and research directions are put forward. Despite remarkable progress, challenges remain in membrane stability, economic feasibility, and large-scale implementation. Therefore, this study outlines the latest materials, mechanisms, and prospects of membrane-based persulfate technology, which are expected to promote its widespread application in environmental governance.
