Reduced Graphene Oxide-Laminated One-Dimensional TiO-Bronze Nanowire Composite: An Efficient Photoanode Material for Dye-Sensitized Solar Cells.

A facile one-step hydrothermal method was developed to prepare reduced graphene oxide-laminated TiO-bronze (TiO-B) nanowire composites (TNWG), which contain two-dimensional graphene oxide nanosheets and TiO-B nanowires. In the hydrothermal process, the functional groups of graphene oxide were reduced significantly. Dye-sensitized solar cells (DSSCs) were fabricated using TNWG as the photoanode material.
