Abstract: One-dimensional TiO2 nanostructures of different structural phases with graphene composites were employed as photocatalysts for photocatalytic H2 production. Two strategies have been explored for enhancement of photocatalytic reactivity. The first is demonstrated through the use of one-dimensional nanostructures, which feature good vectorial electron transport due to decreased grain boundaries. The second strategy is to form a composite/network with two-dimensional reduced graphene oxide (RGO), which features visible light photosensitization and is an efficient charge transporter and separator. It is noted that other than structural design, it is crucial to attain anatase phase structures and superior interfacial contact between GO and TiO2 nanostructures to enable optimal synergy between one-dimensional TiO2 nanostructures and graphene for enhanced photocatalytic H 2 production performance. In this work, hydrothermal synthesis and an in situ solution-based photoreduction method are used owing to their scalability, low temperature, high yield and ease of temperature and reactant concentration control characteristics. © 2013 The Royal Society of Chemistry.
