Abstract: | The power of solid-state NMR for the interrogation of porous catalytic materials is illustrated using three examples. First,
for the investigation of catalytic processes occurring within the confines of a microporous catalyst NMR is shown to reveal
both the details of shape-selectivity and the nature of internal surface species. Second, NMR is shown to be a powerful short-range
tool to reveal precise structural information on highly disordered microporous titanosilicates. Despite long-range disorder
the short-range order is maintained and can be easily studied. Finally, the same utility of probing short-range chemical phenomena
is shown to be crucial for the investigation of novel-ordered-amorphous-mesoporous materials known generically as M41S. This
class of material is currently one of the most important with potential catalytic application. |
