Aqueous immiscible layered double hydroxides – AIM-LDHs

Abstract

Post synthesis treatment of Layered Double Hydroxides (LDHs) with aqueous immiscible solvents (AIM solvents) yields highly dispersible, high surface area materials (up to 377 m2 g−1). The effect of solvent functional groups and structure, initial LDH particle morphology along with parameters such as dispersion time, and solvent recycling properties of AIM-LDHs are explored. The interactions between solvents and LDHs via hydrogen bonding are investigated using high field rapid magic angle spinning (MAS) solid state nuclear magnetic resonance spectroscopy (SSNMR). The strength of the hydrogen bonding interactions that a given solvent can offer appears a crucial factor for the effectiveness of the treatment.
