The article by Dr. Shaghayegh Naghdi reports on a recent study involving the use of mixed-ligand metal-organic frameworks (MOFs) for the removal of glyphosate from contaminated water. In this work the researchers employed a strategy to selectively remove one ligand from the MOFs upon thermolysis, resulting in two distinct hierarchical pore architectures. The resulting hierarchically porous MOFs demonstrated a strong affinity for glyphosate due to the numerous Ti-OH groups resulting from the selective ligand removal, leading to effective glyphosate uptake. The introduction of additional mesopores increased the adsorption capacities by nearly 3 times, making these MOFs among the best-reported adsorbents.
