INVESTIGATION OF THE STABILITY OF POLYCRYSTALLINE n-CdSc PHOTOANODE IN K4Fe(CN)6-EDTA SOLUTION

doi:10.7517/j.issn.1674-0475.1987.02.11

Abstract

Abstract: The effects of various factors on the stabilization efficiency (5) of polycrystalline n-CdSe electrode in the aqueous solution of K₄Fe(CN)₆ containing EDTA were investigated using the rotating ring disk electrode (RRDE). The beneficial effects of metal ion treatments on stability were demonstrated. With Ru ion treatment 5 increased nearly up to unity. In the case of Au, Pt and Pb, S increased by a factor of 2 to 2.5. The presence of metallic layers deposited on the surface of polycrystalline n-CdSe electrode was proved by the analysis of X-ray fluorescence spectra and the Mott-Schottky plots.

Key words: photochemical cells, stability, metal films, n-CdSe cell, photocorrosion
