Exfoliated layered copper phosphonate showing enhanced adsorption capability towards Pb ions†
Abstract
Copper 5-(2-bromothienyl)phosphonate (1) with a layered structure is obtained via solvothermal reaction. The layers can be successfully exfoliated using a “top-down” approach, resulting in 2D nanosheets. The exfoliated sample shows an enhanced adsorption capability to the Pb(II) ions in aqueous solution compared with that of the bulk material.
