Metal organic frameworks (MOFs) find many potential applications because of their versatile physicochemical properties. Advanced oxidation is an important way for wastewater remediation to realize sustainable supply of clean water. However, due to the lack of water-stable MOFs with sufficient catalytic activity, the application of MOFs in advanced oxidation processes (AOP) for wastewater treatment is greatly hindered. In this study, by taking advantage of the rich pores of water stable MOFs, we develop a MOFs-based core (water stable MOFs)-shell (NiP) structure as an efficient catalyst for peroxymonosulfate (PMS) activation in AOP. Here, water stable MIL-96 as the MOFs is synthesized by a hydrothermal method, and the core-shell structured MIL-96@NiP is facilely synthesized through electroless coating of the NiP layer. The as-prepared core-shell structure demonstrates superior performance in catalytic degradation of rhodamine B (RhB), over performing the individual MOFs and NiP parts, suggesting the appearance of synergistic effect between MOFs and NiP in the core-shell structure. Furthermore, the catalyst demonstrates four consecutive runs without losing significant catalytic activity. Temperature has a significant role in faster degradation of RhB. A plausible degradation mechanism is proposed through classical quenching tests study, and oxygen singlet is found to play imperative part in removal of RhB.

金属有机骨架（MOF）由于其多种物理化学特性而发现了许多潜在的应用。高级氧化是废水修复中实现可持续清洁水供应的重要途径。但是，由于缺乏具有足够催化活性的水稳定性MOF，因此大大阻碍了MOF在高级氧化工艺（AOP）中用于废水处理的应用。在这项研究中，通过利用水稳定性MOF的丰富孔，我们开发了基于MOF的核（水稳定性MOF）-壳（NiP）结构，作为AOP中过氧单硫酸盐（PMS）活化的有效催化剂。在此，通过水热法合成作为MOF的水稳定的MIL-96，并且通过化学镀NiP层容易地合成核-壳结构的MIL-96 @ NiP。所制备的核-壳结构表现出优于罗丹明B（RhB）的催化降解性能，优于单独的MOF和NiP部分，表明在核-壳结构中出现了MOF和NiP的协同作用。此外，该催化剂表现出四个连续运行而没有损失明显的催化活性。温度对RhB的更快降解具有重要作用。通过经典的淬灭试验研究，提出了合理的降解机理，发现单线态氧在去除RhB中起着至关重要的作用。该催化剂表现出连续四个运行而没有损失明显的催化活性。温度对RhB的更快降解具有重要作用。通过经典的猝灭试验研究，提出了合理的降解机理，发现单线态氧在去除RhB中起着至关重要的作用。该催化剂表现出连续四个运行而没有损失明显的催化活性。温度对RhB的更快降解具有重要作用。通过经典的猝灭试验研究，提出了合理的降解机理，发现单线态氧在去除RhB中起着至关重要的作用。
