Applications to Catalysis and Environmental Science
Electronic and geometrical structures of NO-Na+ and Cu(I)-NO complexes formed in zeolites are discussed based on the g and the 14N and 23Na hf values evaluated by multi-frequency ESR, pulsed ENDOR and HYSCORE methods. The structure of (NO)2 bi-radical formed in zeolites is discussed based on X- and Q-band ESR spectra. Microenvironment effects on the molecular dynamics and the thermal stability of triethyl- and tripropyl-amine radical cations as spin probes are presented referring to the CW-X-band ESR results and theoretical DFT calculations. X- and Q-band ESR studies on nitrogen-doped TiO2 semiconductor reveal that the diamagnetic N– ion in the system absorbs visible light so as to excite an electron of N– to the conduction band. The photo-catalytic reactions of TiO2 are modified by introducing O2 molecules which scavenge a fraction of photoexcited electrons to generate O2 –. ESR spectral characteristics of adsorbed O2 –, g-tensor and hf structure of labeled 17O (I = 7/2), are presented.
