In-situ Ti3+/S doped high thermostable anatase TiO2 nanorods using ethanediamine-modified TiOSO4 as pre-cursor are synthesized under 700 degrees C calcination, then combined with controllable in-situ solid-phase reaction method, calcined at 350 degrees C in argon. The outcomes declare that the obtained photocatalyst with a high crystallinity is effectively doped with S element and Ti-3(+) species, and synchronously possesses one-dimensional (1D) anatase nanorods structure with length of similar to 2-5 mu m and width of similar to 0.5-1 mu m. The S and Ti-3(+) co-doped 1D nanorod with a narrowed bandgap (2.56 eV) stretches the optical response range to visible-light. The visible-light-driven photocatalytic degradation efficiency of methyl orange and H-2 production rate for Ti3+/S-TiO2 nanorods are as high as 96% and 166 mu mol h(-1) g(-1), showing about 6 times greater than 600-TR (TiO2 nanorods). This is be ascribed to the synergistic reaction of S and Ti-3(+) species co-doping narrows the bandgap and promotes the separation efficiency of photoexcited carriers, and the one-dimensional structure favors the transportation of photogenerated charge carriers. Hence, the prepared photocatalyst will have a great latent application prospect in fields of energy and environment.
