Abstract
The paper describes an electron spin resonance (ESR) study on the interaction of oxygen with ZnO, TiO2 and ZrO2 during photoirradiation. Photoadsorption and photodesorption of oxygen were investigated on these oxides with simultaneous measurements of the ESR spectra due to adsorbed oxygen and of the residual oxygen pressure. Significance of the role of neutral oxygen present on the surface for the photoresponses was emphasized.
