AB - An efficient hierarchical structure, nano-branch containing anatase TiO<inf>2</inf> nanofibers and rutile nanorods, was prepared via the combination of the electrospinning and hydrothermal processes. This novel configuration of TiO<inf>2</inf> multiphase possessed higher surface area, roughness, and fill factors compared with each single phase component prepared in the same condition, which significantly enhanced its light absorption. Our experimental results showed that within the interface of multiphase TiO<inf>2</inf>, the heterojunction promoted the charge separation and improved the charge transfer rate, leading to higher efficiency for photoelectrochemical water splitting. The photocurrent density of the nano-branched TiO<inf>2</inf> electrode could reach 0.95 mA/cm<sup>2</sup>, which was almost twice as large as that of the pristine TiO<inf>2</inf> nanorod. Our work provides a simple and feasible routine to synthesize complex TiO<inf>2</inf> nanoarchitectures, which lays a foundation for improving energy storage and conversion efficiency of TiO<inf>2</inf>-based photoelectrodes.
