Direct Observation of Various Al Sites in SAPO-34 by 27Al Multiquantum (MQ) Magic Angle Spinning (MAS) NMR
摘要:
The elegant 2D multiquantum (MQ) MAS NMR has been applied to invcstigatc the coordination of Al atoms in SAPO-34. The results show that the effects of the template and/or water on the coordination of Al atoms are significanl, which lead to the formation of various Al species. Up to four kinds of Al species are distinctly resolved.
