Title: Bipolar TiO/sub 2//Pt semiconductor photoelectrodes and multielectrode arrays for unassisted photolytic water splitting

Abstract

Bipolar TiO/sub 2//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, O/sub 2/ electrolytes, were constructed. In series configuration, the open-circuit voltage V/sub oc/ is proportional to the number of panels used. With five panels in series, a V/sub oc/ in excess of 3.6 V is obtained, permitting unassisted photolytic (Xe lamp) water splitting to produce H/sub 2/ and O/sub 2/.
