In this study, Fe@Fe2O3 core - shell nanowires were first used as a novel Fenton iron reagent. The nanowires were synthesized through the reduction of ferric chloride aqueous solution by sodium borohydride at ambient atmosphere, without protection of inert gases or vacuum. Rhodamine B (RhB) could be efficiently degraded in aqueous media by a novel sonochemical-assisted Fenton (sono-Fenton) system based on these Fe@Fe 2O3 core-shell nanowires. The RhB degradation processes were monitored by UV-vis spectroscopy and total organic carbon (TOC) analysis. Fe@Fe2O3 core-shell nanowires showed much hi...
