Spatial confinement of a cationic MOF: a SC–SC approach for high capacity Cr(<scp>vi</scp>)-oxyanion capture in aqueous solution

Abstract

A water-stable cationic MOF could be used as a single crystal container to capture Cr(vi)-oxyanions via ion exchange with high capacity and selectivity. It is the first report that demonstrates that CrO42- ions could be traced and confirmed via a single-crystal to single-crystal (SC-SC) pattern.
