ANATASE-RUTILE TRANSFORMATION IN FE/TIO2, TH/TIO2 AND CU/TIO2 CATALYSTS AND ITS POSSIBLE ROLE IN METAL-SUPPORT INTERACTION.
27 - 36.
Based on in-situ Mossbauer and X-ray diffraction studies, it is shown that in the Fe/TiO2 catalyst, the anatase-rutile transformation of the TiO2 support is facilitated by the Fe2+ ions formed during the reduction. The transformation occurs at lower temperatures in Th/TiO2 and Cu/TiO2 compared to pure TiO2. In general, the transformation of anatase to rutile seems to occur at or below the temperature (approximately 770 K) at which strong-metal-support-interaction manifests itself.
