New functional materials for heavy metal sorption: "supramolecular" attachment of thiols to mesoporous silica substrates.
A new class of sorbent material, which exhibits exceptional metal capture from contaminated natural water, features aromatic thiol ligands reversibly bound to functionalized mesoporous silica through non-covalent interactions and have the potential of being regenerable.
