Exfoliation of a two-dimensional cationic inorganic network as a new paradigm for high-capacity CrVI-anion capture

Abstract

We have discovered a rare example of a non-LDH cationic inorganic layered material [Cu4(OH)6][O3S(CH2)4SO3]. Its in situ exfoliation achieves record high adsorption capacities for chromate and dichromate. This phenomenon is ascribed to the combination of the strong host–anion electrostatic interactions and the high surface area of our cuprate material, which overcomes the memory effect problem of LDHs. Moreover, our material also selectively captures CrVI with a negligible decrease in capacity when non-toxic, monovalent anions are present.
