Recent Advances of Solid-State NMR Studies on Zeolites
2013, Annual Reports on NMR SpectroscopyCitation Excerpt :Cadars and coworkers39 proposed that 29Si J-coupling interaction could be used as a sensitive probe for the local structure of zeolite frameworks and offer new opportunities for refining and solving complicated zeolite structures. 129Xe NMR has been used to characterize the pore structure and adsorption behaviour in various porous materials such as MCM-22, MAS-7 and ZSM-5.47–50 By using 129Xe NMR, Chen et al.47 found that Xe atoms were preferentially adsorbed in the supercages of zeolite MCM-22 at low Xe pressure, while Xe atoms could penetrate into the two-dimensional sinusoidal channels at high Xe pressure.

2011, Catalysis TodayCitation Excerpt :The extrapolation to zero xenon pressure gives us the term δS, and the slope is given by the δXe–Xe interactions. For HZSM-5 zeolites [27], there is a linear relation between the chemical shift of xenon and the xenon pressure at high Xe pressures. But for low Xe pressures, a minimum for the chemical shift was observed, which then increases sharply (similarly as for the line width) as the pressure decreased further.
