TiO 2 nanoparticle film catalysts with different thicknesses were prepared by plasma enhanced chemical vapor deposition(PECVD) method and the surfaces were subsequently treated by TiCl 4 or O 2 plasma. Two kinds of Ti...
The amorphous V 2O 5 films prepared by vacuum evaporation are unstable and easily dissolved by electrolyte during the electrochromic process, so unfit to make electrochromic materials. We found that the annealed films...
