摘      要：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 HN03 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.
