Partially Fluorinated Alumina With Enhanced Stability: Application To Catalysis Under Aggressive Conditions

Here, we report the design of new aluminum hydroxyfluoride, mainly composed of amorphous phase, with enhanced stability under HF gas in term of textural properties, especially the specific surface area and the acidity. The material has been synthesized through an EISA (evaporation‐induced self‐assembly) route using liquid crystals as templates. Thanks to this stability, the catalyst designed by the dispersion of the active phase on this support shows a higher accessibility and activity of the active sites than the ones obtained by other methods
