| 英文摘要 | We demonstrated that the heteronuclear correlation experiments between two quadrupolar nuclei, Na-23 and Al-27, with close Larmor frequencies can be achieved via D-HMQC and D-RINEPT approaches by using a diplexer connected to a conventional probe in magic-angle-spinning solid-state NMR. Low-power heteronuclear dipolar recoupling schemes can be applied on Na-23 or Al-27 to establish polarization transfers between the central transitions of Na-23 and Al-27 for a model compound, NaAlO2. Further, we showed a practical implementation of the two dimensional Na-23-Al-27 dipolar -based heteronuclear correlation experiment on a heterogeneous catalyst, Na2CO3/gamma-Al2O3. This allows to determine spatial proximities between different Na-23 and Al-27 sites, thus the surface Na species adjacent to octahedral -coordination Al can be clearly discriminated. |
