Description
A continuous flow hyperpolarized (HP) 129Xe NMR spectroscopy was employed for the first time to investigate TiO2 nanotubes (Ti-NTs) synthesized from commercial nanoparticles with different reaction times. A single peak attributing to channels for Ti-NTs was observed for variable temperature HP 129Xe NMR spectra. It was also noted that there is alteration in value for heat of adsorption, ΔH from 12.6 ± 1.3 to 16.4 ± 0.4 kJ/mol and variation in chemical shift of the xenon adsorbed in channels, δs from 120 ± 2 ∼ 135 ± 9 ppm which were closely correlated to channel length and it was shown that P25-24 Ti-NTs with longest channel is most favorite Ti-NTs for Xe adsorption
