The photoelectrochemical response of electrodes of single crystals of the layer-type compound n-ZrS/sub 2/ prepared by vapor transport in Fe/sup 3+//Fe/sup 2+/, ferrocyanide/ferricyanide, and iodide solutions was investigated. The flatband potential (V/sub FB/) of the electrode in 1M NaCl and 0.032M HCl solutions, estimated from impedance measurements, was -0.40V vs. SCE at pH 1.5 and shifted towards more negative values by 54 mV/unit pH change to pH 12. A two-electrode photoelectrochemical cell with a n-ZrS/sub 2/ anode and Pt gauze cathode in a 0.10M FeCl/sub 2/, 0.10M FeCl/sub 3/, and 1.0M HCl electrolyte gave a short-circuit photocurrent of 15 mA/cm/sup 2/ and an open-circuit photovoltage of 0.4V under xenon lamp illumination (ca. 100 mW/cm/sup 2/).
