New efficient intercalation of bioactive molecules into layered double hydroxide materials by solid-state exchange: An in situ XRPD study

A new soft and fast solid state reaction is exploited for the preparation of exchanged layered double hydroxide materials and, in particular, for intercalating bioactive molecules. The characterization of the nanocomposite, carried out by crystallographic and thermogravimetric techniques, revealed that this synthesis yield is comparable to that of standard methods but with time, solvent, and energy saving advantages. Moreover, the in situ diffraction experiments also allowed us to shed some light on the kinetics of the intercalation process.
