Traditional adsorbents using silver nanoparticles demonstrated exceptional adsorption capacities for Br–. However, the majority of sites in are situated on their surfaces, limiting interaction internal atoms with Therefore, we synthesized Ag/UiO-bpy MOF by utilizing two pyridine nitrogen ligand to anchor silver. So each atom was effectively exposed. Besides, owing coordinatively unsaturated state atoms, they exhibited a stronger affinity As result, an Br– capacity 362.6 mg/g. Notably, respect 2083.9 mg/gAg, which surpasses all previously reported values literature. Furthermore, rapid kinetics and selectivity experiments. This work not only fabricated adsorbent high but also proposed new innovative strategy subsequent preparation adsorbents.
