Abstract

Abstract: The competitive oxidation reaction of hole between the reducing agent K₄Fe(CN)₆ and n-CdSe photoanode was studied by RRDE.The results proved that the photogenerated holes are captured directly from the valence band.After modification of ferrocenylene-octadecanoate L-B films,the competitive oxidation effect of reducing agent is enhanced and the stabilization efficiency of the electrode was increased for about 20%.

Key words: n-CdSe electrode, photoelectrochemistry, L-B technique, modified electrode
