文摘

Fe₃O₄@ZnO nanospheres were synthesized by a chemical method and characterized using various analytical instruments. Products were characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectra, X-ray diffraction and vibrating sample magnetometer. The results showed that Fe₃O₄@ZnO nanospheres exhibited high degree of crystallinity and excellent magnetic properties at room temperature. Photocatalytic investigation of Fe₃O₄@ZnO core/shell nanospheres was carried out using rhodamine B solution under UV light. Fe₃O₄@ZnO core/shell nanospheres showed enhanced photocatalytic performance in comparison with the as prepared ZnO nanoparticles. Additionally, the recycling experiment of Fe₃O₄@ZnO nanospheres had been done, demonstrating that Fe₃O₄@ZnO nanospheres have high efficiency and stability.
