Abstract

Nanosheets of Caand Y, with COin the interlayer with a uniform diameter and lengths of several tens of microns have been successfully synthesized in a hydrotalcite layer structure (a layered double hydroxide), using a hydrothermal method. The formation mechanism of lamellar CaY—COlayered double hydroxides (LDHs) depends on the molar ratio of Ca and Y and the reaction time and temperature. The resulting LDH materials exhibit excellent affinity and selectivity for heavy transition metal and metalloid ions.
