Structure and catalytic characterization of a second framework Al(IV) site in zeolite catalysts revealed by NMR at 35.2 Tesla

Ultra-high field (27)Al{(1)H} 2D correlation NMR experiments demonstrate that at least two framework Al(IV) sites with hydroxyl groups can exist in acidic zeolite catalysts in their dehydrated and catalytically active states. In addition to the known Al(IV) at the framework bridging acid site (BAS),...
