Advances in the characterization of inorganic solids using NMR correlation experiments

“…Similar approaches have been used to probe proximities between protons and other spin-1/2 isotopes, such as 15 N 195,216 , 19 F 365 , 29 Si 90 and 195 Pt 227 , near surfaces (see Figure 18). Furthermore, through-space heteronuclear correlation experiments have also been applied to probe proximities between protons and half-integer quadrupolar nuclei, such as 11 B 116,366 , 17 O 288,367 and 27 Al 292,[368][369][370][371][372][373] . These experiments allow notably the selective observation of 11 B, 17 O and 27 Al nuclei located near the surface of oxide or nitride phases since their bulk region does not contain protons.…”

“…These experiments allow notably the selective observation of 11 B, 17 O and 27 Al nuclei located near the surface of oxide or nitride phases since their bulk region does not contain protons. In particular, 2D 27 Al{ 1 H} D-HMQC experiment has been employed to identify the hydroxyl groups at the surface of γ-alumina 292 and the preferential grafting sites of metal complexes on these surfaces (see Figure 31) 369 as well as the nature of Brønsted acid sites near the surface of amorphous silica alumina 368,373 . Furthermore, 2D 11 B{ 29 Si} and 27 Al{ 29 Si} D-HMQC experiments have been used to probe the anchoring of BN/B2O3 and Al2O3 phases on silica nanoparticles (see Figure 25b) 285,372 .…”
