Photo-assisted corrosion

We have previously analyzed the photo-assisted corrosion of n-type materials during photoanode applications (8). This work suggested that the H+ ions produced during the electrolysis reaction underwent desorption from the photoanode surface much less readily than would be suspected for fully hydrated H+ ions, and is summarized in Appendix I. [Pg.309]

We propose that this observed photo-assisted corrosion occurs via the following mechanism ... [Pg.327]

A full description of photo-assisted semiconductor corrosion is not available. We have undertaken an analysis of this phenomena, relying on aqueous solution electrochemical equilibria considerations (16). [Pg.327]

In the presented case CdS, as a prominent example for nano structured n-VI semiconductors, were used since their lower band gaps compared to corresponding oxide materials make them attractive candidates for visible light assisted photocatalytic hydrogen generation. The hole scavenger TEA protects the CdS from anodic photo corrosion (caused by oxidation reactions, i.e. CdS + 2h Cd - + S) by swiftly... [Pg.22]
