Keynote: Organic Chem Curr Res
A critical overview is presented of zeolites and their use in practical applications. Specifically considered are their roles as media for selective light-induced oxidations of organic molecules using molecular O2, and the relationship between this phenomenon and the surface electric fields that exist in zeolites. Methods for determining the strength of the zeolite surface fields are discussed using sorbed molecules such as CO with IR detection, and the spin-probes, di-tert-butyl nitroxide and NO, as detected using EPR spectroscopy. The relationship between these surface fields and molecular reorientation energetics for organic free radicals sorbed in zeolites, obtained using muonium as a spin-label, is explored. Finally, results obtained from exposing the naturally occurring zeolite, clinoptilolite to high energy electrons as a means for activating the material toward the selective removal of radioactive caesium and strontium cations from the wastewaters of nuclear power plants are presented Recent publications 1.
