Brønsted acid sites based on penta-coordinated aluminum species

Until now, it has been believed that Brønsted acid sites in amorphous silica-alumina are formed from only tetra-coordinated (AlIV) sites. Here, the authors use 27Al-{1H} correlation NMR experiments to identify a new AlV-based Brønsted acid site, with implications for increasing the acidity of solid...
