Atomic layer deposition of aluminium on anatase: A solid acid catalyst with remarkable performances for alcohol dehydration

Here we reported the synthesis of Al sites with ultra-high dispersion on anatase by an atomic layer deposition (ALD) method (ALD-Al/TiO2), which exhibits Brønsted acidity and satisfactory activity in the dehydration of alcohols, a key step in the deoxygenation of biomass. More importantly, the ALD-Al/TiO2 catalyst has good stability, which is sintering-resistant and gives constant catalytic performances after treatments at high temperature.
