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. 29Si MAS 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 zeolite of the samples with close Al is utilized to identify the locations of the corresponding Al–O–(Si–O)2–Al pairs in a ring.
