Fluoride materials

In contrast, other fluoride materials or LaF3 precipitate in a polymeric matrix are not suitable. 

In contrast, like in oxide systems, amorphous high-surface fluoride materials for catalytic purposes can be synthesized from organic solvents and anhydrous HF, as shown recently for HS-AlFs (HS = high surface).

The first part of this chapter undertakes an introduction to microwave synthesis. After presenting the origin of this technique, some basic concepts of microwave heating are described and the advantages offered by this route are briefly discussed. Finally, a typical microwave oven dedicated to the synthesis is shown. Some examples of nanosized metal fluorides prepared by microwave irradiation are presented in the subsequent section. Particular attention is given to the preparation of nanosized aluminium-based fluoride materials. The impact of some synthesis parameters is discussed and a detailed characterization of the Al-based compounds is proposed to highlight the potential of this preparation route.

Homonuclear fluorine spatial proximities can be evidenced through 2D V DQ-SQMAS correlation NMR experiments [59] as shown in oxyfluoride [60] and in fluoride materials [57,61-63] leading to the assignment of F MAS NMR spectra. In these examples, the... 

All these studies show that both F and Al 61 0 of A10e xFx environments increase with the oxygen content. These findings are essential for the NMR investigations of disordered Al-based fluoride materials discussed in the following.
