Photoelectrochemical Water Oxidation

Opposite contributions of graphene oxide are obtained in TiO2 nanorod array photoanodes, in electrolytes of varying pH, for the water splitting application. The photocurrent of TiO2 photoanode is improved, after graphene oxide coating, in a neutral pH electrolyte, while it decreases in a basic electrolyte.
