[Raman spectrum research on structure and performance of nanometer TiO2 film photocatalyst supported on stainless steel netweb].
Crystal structure, particle size and thickness of film titania as photocatalyst on stainless steel netweb synthesized by sol-gel was studied by Raman spectroscopy. It was showed that diffusion of Fe in the base was banned when certain thickness of the film was obtained; when the film was calcined at 400 degrees C, it was anatase, and when the calcining temperature exceeded 400 degrees C, rutile came up in the film. The characteristic Raman peak of anatase shifted, which showed that the particle size of the film was changing, and from calculating, the size was about 10.7 nm. TEM result was consistent with it.
