Ideal photoanodes for the efficient photoelectrolysis of water with solar energy would be low electron affinity, robust oxide semiconductors with band gaps which are less than approx. 2.5 eV. It is probable that only d-band oxides would have valence bands high enough in energy to give rise to this combination of properties. In order to produce such materials, highly insulating perovskites and rutiles have been substituted with d/sup n/ transition metals. Sensitization of photocurrents to the visible portion of the spectrum was noted in several cases, although in this series of compounds, the photocurrent quantum yields were decreased by the substituents. 4 figures, 2 tables.
