Description Photoelectrochemical (PEC) stability of lead oxide (PbO(n)) in Fe(CN)6(-4) solution with alkali halides at pH 9.2 has been studied. Among the alkali halides studied, KI (0.1 M) enhances the stability of PbO(n) by 80%. This stability enhances further if solution is made from a saturated solution of PbO. A model is developed to explain the role of KI in suppressing the photocorrosion of PbO(n). A special arrangement is designed for illuminating disc/ring electrode assembly of rotating rind disc electrode (RRDE) as well for electrode of a PEC cell to minimize the loss of light intensity due to its absorption by coloured solution. Alkali halides MX (M = Li, Na, K and Cs; X = Cl, Br, and I), have been used for this study.
