Role and Fate of Hematite in Titania Coated Hematite Photocatalysts

Abstract This paper presents the characteristics of two different titania-hematite composite systems, namely titania-colloidal hematite particles and titania-nano hematite particles, and their use as photocatalysts. The transmission electron micrographs showed that the colloidal hematite particles were capped with layers of TiO
