Abstract

Super acidic solids: A new two-step route to high-surface-area metal fluorides is reported, by which amorphous AlF3 can be prepared having a BET(N2) surface area of more than 200 m2 g−1 (see SEM image). This HS-AlF3 shows a very high Lewis acidity and consequently a high catalytic activity.
