The preparation of Fe doped TiO 2 is demonstrated as well as application for gas sensing and photocatalytic degradation. Fe doped TiO 2 nanopowder was prepared by the mechanochemical ball milling method. The results show the uniform doping of Fe in TiO 2 powder. The average size of the particle is observed to be ∼28 nm. The H 2 gas sensor was fabricated using the Fe doped TiO 2 nanopowder and the effect of Fe doping on the sensing properties is investigated with various temperature ranges. The prepared Fe doped TiO 2 nanoparticles are also used to explore degradation properties of Rhodamine B dye under LED light.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
