Photocorrosion Mechanism of TiO2-Coated Photoanodes by Arjen Didden, Philipp Hillebrand, Bernard Dam, Roel van de Krol

“…The degradation of the film initiates from small pinholes and shows oscillatory behavior that can be explained by an Avrami-type model for photocorrosion that is halfway between 2D and 3D etching. XPS analysis of corroded films indicates that a thin layer of CdS remains present on the surface of the corroded photoanode that is more resilient towards photocorrosion.…”
