“…In the literature, there are various data about the effect of the external potential on the results of impedance spectroscopy. In the case of ZnS deposited on ITO, resistivity decreases with the growth of the external potential from 0 to 1 V [27]. The composite catalyst consisting of titania and graphene oxide demonstrates the same properties: the radii of the hodographs decrease with the increase of the external potential from 0 to 0.5 V [28].…”

In this paper, the dependences of the semiconductors’ photoelectrochemical properties on the experimental conditions were studied for the solid solution of CdS and ZnS, graphitic carbon nitride, and the platinized carbon nitride. The cyclic voltammograms were obtained under different scan rates. The sample investigations were carried out by two ways, at the constant external voltage and varied amplitudes and at different external voltages and the fixed amplitude. The Mott – Schottky dependences were studied at different frequencies. The basic dependences of the changes in the photoelectrode target characteristics on the experimental condition were found. Some recommendations for the correct comparison of qualitative and quantitative photoelectrochemical data were formulated.
