Abstract:Perovskite ferroelectric K 1−x Na x NbO 3 (x = 0, 0.05, 0.1, 0.3, 0.5, 0.7, and 1) nanofibers were prepared by electrospinning. The effects of Na doping on the photocatalytic hydrogen production of K 1−x Na x NbO 3 were studied. The results revealed that the best hydrogen production rates were at x = 0.5, which were 230.12 and 0.66 μmol•h −1 under simulated sunlight and visible light irradiation, respectively. Conversely, the corresponding hydrogen production rates of pure KNbO 3 were 155.90 and 0 μmol•h −1 , … 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.
