摘要：

An impedance study of the p-RuS//2/aqueous electrolyte interface confirms the existence of a Fermi level pinning of the semiconductor. The mechanisms of the band shift and of the interaction with a redox couple are illustrated. The photopotential is limited by the moderate quality of the barrier which allows forward currents flowing through the interface. The effect of the interface modification by means of a metal deposition on the semiconductor surface has been investigated. An improvement in the catalysis with respect to both photoassisted hydrogen evolution and oxygen dark reduction was found.
