  Ni-doped TiO2 film catalysts were prepared by a plasma   electrolytic

  oxidation (PEO) method and were mainly characterized by means of   SEM, EDS, XRD,

  XPS, and DRS, respectively. The effects of Ni doping on the   structure,

  composition and optical absorption property of the film catalysts   were

  investigated along with their inherent relationships. The results   show that the

  film catalyst is composed of anatase and rutile TiO2  with microporous

  structure. Doping Ni changes the phase composition and the   lattice parameters

  (interplanar crystal spacing and cell volume) of the films. The   optical

  absorption range of TiO2 film gradually expands and   shifts to the red

  with increasing dosages. Both direct and indirect transition band   gaps of the

  TiO2 films are deduced consequently. Moreover, the   photocatalytic

  activity of the film catalysts for splitting

  Na2S+Na2SO3 solution into   H2 is

  enhanced by doping with an appropriate amount of Ni. The   as-prepared

  TiO2 film catalyst doping with 10 g/L of   Ni(Ac)2 presents

  the highest photocatalytic reducing activity.
