Complex Analysis of the Aluminum Siting in the Framework of Silicon-Rich Zeolites. A Case Study on Ferrierites
Original language description
We present a multistep method combining multispectroscopic experiments with DFT calculations to determine the complete Al distribution in silicon-rich zeolites, independent of the presence of Al?O?(Si?O)n?Al (n = 1, 2) sequences in their frameworks. 29SiMAS NMR spectroscopy is employed to confirm the absence of Al?O?Si?O?Al in the framework of silicon-rich zeolites while 27Al 3Q MAS NMR spectroscopy and DFT computations of 27Al isotropic chemical shifts serve to determine the locations of isolated Al atoms. The maximum ion-exchange capacity of zeolites for [Co2+(H2O)6]2+ reveals the presence of close Al atoms (i.e., those Al atoms which are able to balance [Co2+(H2O)6]2+ ions). Then visible spectroscopy of the bare Co(II) ion in the dehydrated zeoliteof the samples with close Al is utilized to identify the locations of the corresponding Al?O?(Si?O)2?Al pairs in a ring.
