The existence of organic micropollutants (OPMs) in water poses a considerable threat to the environment. A centralized approach towards pollutants abatement has dominated over the recent decades wherein heterogeneous Fenton-like based advanced oxidation processes can be a promising technology. The application of engineered nanomaterials offers more opportunities to enhance their catalyst properties. This study synthesizes a series of ultrathin two-dimensional (2D) Metal-organic frameworks (MOFs) nanosheets with tunable metal clusters. The formation of reactive oxygen species (^•OH and ¹O₂) can be significantly boosted via transferring the adsorbed H₂O₂ onto the solid-liquid interface by systematically tuning the metal species. The Co-MOF nanosheets exhibited an ultrafast degradation kinetic for BPA with a rate of 2.23 min⁻¹ (4.98 times higher than that of the bulk MOF) and TOF (turnover frequency) value of 9.99 min⁻¹, which are observably greater than that of the existing materials reported to date. Density functional theory simulation and experimental results unravel the mechanism for ROS formation, which is strongly metal-depend. We further loaded the powder onto a flow-through poly (vinylidene fluoride) (PVDF) microfiltration membrane and observed that the representative OPMs could be rapidly degraded, indicating promising properties for practical application.

水中有机微污染物（OPM）的存在对环境构成了相当大的威胁。近几十年来，集中式减少污染物的方法占主导地位，其中基于异质类芬顿的高级氧化工艺可能是一种有前途的技术。工程纳米材料的应用为增强其催化剂性能提供了更多机会。本研究合成了一系列具有可调金属簇的超薄二维 (2D) 金属有机框架 (MOF) 纳米片。_{通过转移吸附的 H 2} O ₂可以显着促进活性氧（^• OH 和¹ O _{2 ）的形成}通过系统地调整金属种类到固液界面上。Co-MOF纳米片表现出对BPA的超快降解动力学，速率为2.23 min ^-1（比块体MOF高4.98倍），TOF（周转频率）值为9.99 min ^-1，明显大于迄今为止报告的现有材料。密度泛函理论模拟和实验结果揭示了强烈依赖金属的 ROS 形成机制。我们进一步将粉末加载到流通式聚（偏二氟乙烯）（PVDF）微滤膜上，并观察到代表性的 OPM 可以快速降解，这表明在实际应用中具有良好的性能。
