Abstract

Bipolar TiO₂/Pt photoelectrodes were fabricated by anodization of thin Ti foils onto which Pt had been previously sputter-deposited. These photoelectrodes are capable of a vectorial charge transfer. Current-potential curves were used to predict the behavior of multielectrode arrays. Several different multielectrode cells, utilizing KOH, O₂ electrolytes, were constructed. In series configuration, the open-circuit voltage V_oc is proportional to the number of panels used. With five panels in series, a V_oc in excess of 3.6 V is obtained, permitting unassisted photolytic (Xe lamp) water splitting to produce H₂ and O₂.
