TLDR
In this paper, N-type tungsten trioxide is shown to be a stable semiconducting anode for the photoelectrolysis of water and a band gap of 2.7 eV provides a factor of three increase in the utilizable solar spectrum as compared to TiO 2.About:

Photoelectrolysis of water in cells with SrTiO3 anodes
TL;DR: In this paper, the photoelectrolysis of water in cells with SrTiO3 anodes has been confirmed, and the maximum external quantum efficiency at zero bias voltage is 10% (at hν=3.8 eV), about an order of magnitude higher than the maximum value obtained with anodes of TiO2, the only other material so far known to catalyze photoelectronry, and in agreement with the energy level model proposed previously, the efficiency is increased because the band bending at the anode surface is about 0.2 eV larger for
