Abstract

This study examined a water-splitting system comprising a TiO2 photoanode and an organo-photocathode consisting of a p-n bilayer. Stoichiometric decomposition of water into H2 and O2 successfully occurred at bias voltages lower than the theoretical value (i.e. 1.23 V). Compared to the conventional TiO2 and Pt systems, the proposed water-splitting system demonstrated water splitting without any externally applied bias.
