Tetrapropylammonium Occlusion in Nanoaggregates of Precursor of Silicalite-1 Zeolite Studied by 1H and 13C NMR
The dynamic behavior of tetrapropylammonium (TPA) cations in the clear precursor sols for silicalite synthesis has been investigated by 1H diffusion ordered spectroscopy (DOSY), T1, T2, and T1ρ 1H relaxation, as well as 1HÑ13C cross polarization (CP) nuclear magnetic resonance. The DOSY NMR experiments showed the presence of strong solute–solvent interactions in concentrated sols, which are dec...
متن کاملUltra-thin zeolite films prepared by spin-coating Silicalite-1 precursor solutions
A procedure has been developed to prepare ultra-thin zeolite films supported on Si(1 0 0). Films were prepared by spin-coating a solution of Silicalite-1 zeolite precursors diluted in ethanol, followed by hydration in water vapour and heating to 60 C. High resolution transmission electron microscopy analysis of sample cross-sections shows that the surfaces are both smooth and continuous, and fi...
متن کاملThermodynamics, Solvents effects and 1H ,13C NMR Shielding :Theoretical studies of Adamantane
Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...
متن کاملSite-Hopping Dynamics of Benzene Adsorbed on Ca-LSX Zeolite Studied by Solid-State Exchange 13C NMR
First-time applications of solid-state exchange 13C NMR techniques to the study of the reorientation dynamics of hydrocarbon molecules adsorbed on zeolites have enabled the geometry and time scales of molecular hopping processes between adjacent adsorption sites to be characterized directly and model free. Two-dimensional exchange 13C NMR on static samples establishes the geometry of the site-h...
