SrTiO3has a more (~300 mV) negative conduction band energy than TiO2 and thus considered tobe a better semiconductor for driving the photocatalytic water splittingreaction without external bias. However, its net photocurrent generationefficiency is relatively lower than anatase TiO2 itself.  Wehave now succeeded in developing TiO2-SrTiO3compositestructures with enhanced photocatalytic efficiency. TiO2nanotube arrays formed on Ti substrate by electrochemical anodization have beenmodified by pulsed laser deposition of SrTiO3 nanostryctures. Thephotocatalytic properties of TiO2-SrTiO3heterostructures can be modulated by varying the experimental conditions of SrTiO3deposition.  The role of TiO2 basednanoarchitectures in photocatalytic hydrogen production will be presented.
