Abstract

A simple novel synthesis route to aluminum fluoride, AlF₃, from aqueous phase is reported. Al₂O₃ is dissolved in aqueous hydrofluoric acid, HF, and re-precipitated as AlF₃ · 3H₂O. Thermal decomposition results in thermally stable AlF₃ with high specific surface areas between 120 and 60 m²/g depending on treatment temperatures (up to 450 °C). Bulk and surface structures of the resulting amorphous and crystalline materials were characterized by X-ray powder diffraction, infrared and solid state NMR spectroscopy (²⁷Al, MAS), nitrogen physisorption and adsorption of paramagnetic probe molecules (vanadium complexes).
