a Schematics illustrating the facile procedure of H2 treated S, N-doped TiO2 nanorod arrays. b Optical image of the S, N-doped TiO2 nanorod arrays under the various annealing condition. c XRD spectra and d SEM images for the 350 °C post-annealed S, N-doped TiO2 samples under various H2 treatment temperature. The XRD spectra were indexed using the JCPDS crystallographic database. (#00-021-1276)
