AB  - One-dimensional (1-D) TiO(2) nanorod arrays (NRAs) with large inner surface area 
      are desired in dye-sensitized solar cells (DSSCs). So far, good performance of 
      DSSCs based on 1-D rutile TiO(2) NRAs remains a challenge mainly owing to their 
      low dye-loading ability resulting from the insufficient specific surface area of 
      1-D TiO(2) nanostructures. In this paper, densely aligned TiO(2) NRAs with 
      tunable thickness were grown directly on transparent conductive fluorine-doped 
      tin oxide (FTO) substrates by hydrothermal method, followed by a facile chemical 
      etching route to further increase the specific surface area of the TiO(2) NRAs. 
      The etching treatment leads to the split of TiO(2) nanorods into secondary 
      nanorods with a reduced diameter, which markedly enlarges the inner surface area 
      of the TiO(2) NRAs. The formation of 1-D rutile TiO(2) nanotube arrays (NTAs) is 
      observed as well in the etched TiO(2) films. Finally, a DSSC efficiency of 5.94% 
      was achieved by utilizing an etched TiO(2) NRA as the photoanode, which is so far 
      the best DSSC efficiency that has been reported for the 1-D rutile TiO(2) NRA 
      films.
