A novel magnetically separable visible-light-photocatalyst,magnetite/N-doped carboxylate-rich carbon spheres(N-MCRCSs),was synthesized by a facile ultrasonic method using the magnetite/carboxylate-rich carbon spheres(MCRCSs)as precursors.N element has been successfully doped into the MCRCSs in a HNO₃ aqueous solution via an ultrasonic treatment,which were demonstrated by the FT-IR and XPS.N-MCRCSs exhibit more intensive absorption over MCRCSs in the entire UV and visible region.N-MCRCSs can not only be easily recycled by applying an external magnetic field,but also exhibit powerful visible light photocatalytic activity.
