Abstract:TiO 2 being a wide band gap semiconducting material cannot use the solar insolation for photocatalysis. An interesting strategy is to dope TiO 2 with upconverting rare earth materials, which upon infrared (IR) or visible light irradiation can emit ultraviolet light to generate excitons in TiO 2 for further catalytic reactions. This manuscript reports the incorporation of Er 2 O 3 /Yb 2 O 3 into TiO 2 via two synthetic methodologies. One of which yields the co-presence of rare earth oxides and TiO 2 on the surf… Show more
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.
