Photochenistry And Photophysics Of Materials In Zeolites.

  • Kai-Kong Iu (a1), Xinsfleng Liu (a1) and J. Kerry Thomas (a1)

Abstract

Pyrene is used as a molecular probe to study surface polarity, constrained character of diffusion, oxygen diffusion, effects of coadsorbed water, and exchange cations in zeolites A, X and Y. The experimental methods include both steady-state and time-resolved fluorescence spectroscopy, and diffuse reflectance absorption spectroscopy. The properties of CdS and TiO2 constructed in zeolites are also presented.
