Immobilization of imidazolium ionic liquids on hydrotalcites using silane linkers: retardation of memory effect

Abstract

We report a new covalent surface immobilization of silane-modified imidazolium ionic liquids on hydrotalcite-like materials (HTs) and provide detailed characterization of the resulting surface chemistry using PXRD, CP-MAS, TGA and FT-IR. We show that this immobilization interferes with the “memory effect” of HTs and explore the stability of the resulting complexes to hydrolysis.
