CHARACTERIZATION OF AlPO- AND SAPO-BASED MESOSTRUCTURED MATERIALS BY SOLID-STATE NMR

摘要

We have utilized the heteronuclear dipolar-coupling based ~(27)Al/~(31)P double- and ~1H/~(29)Si/~(27)Al triple-resonance solid-state NMR experiments such as cross-polarization (CP), transfer of populations in double-resonance (TRAPDOR), and rotational echo double-resonance (REDOR) to characterize several aluminophosphate (AlPO)- and silicoaluminophosphate (SAPO)-based mesostructured materials.
