1D to 3D NMR study of microporous alumino-phosphate AlPO4-40

abstract

From one- to two- and three-dimensional MAS NMR solid-state experiments involving P-31 and Al-27, we show that the structure of microporous alumino-phosphate AlPO4-40 contains at least four times more sites than expected, and we attribute two types of Al-IV sites. The newly described Al-27-P-31 MQ-HMQC opens new possibilities of describing details of three-dimensional bounded networks. Copyright (C) 2009 John Wiley & Sons, Ltd.
