Aluminum oxide (alumina) exhibits acidic properties, specifically acting as a Lewis acid due to active surface sites.

The analysis

The retrieved literature consistently supports the well-established chemical fact that aluminium oxide possesses acidic properties, specifically characterized by Lewis acid sites on its surface. Papers [0] and [6] explicitly examine or utilize these acid sites in alumina and related aluminum-based materials.
