英文摘要:

      Reduced graphene oxide/iron oxide (RGO/Fe3O4) nanocomposites, which integrate the advantages of RGOand Fe3O4 nanoparticles, are novel magnetic nanomaterials. In recent years, RGO/Fe3O4 nanocompo-sites have exhibited infinite charm in theoretical research and practical application sowing to their excellent mechanical, electrical, optical and thermal properties such as large surface area, high stability and superparamagnetism. This review reported the research progress of RGO/Fe3O4 nanocomposites in magnetic solid phase extraction, lithium ion battery, sensor materials, electromagnetic wave absorption, catalysts, enzyme immobilization, drug delivery and magnetic switches in recent years. The application of RGO/Fe3O4 in magnetic solid phase extraction was reviewed emphatically and the analysis objects including dyes, metal ions, pesticides and veterinary drugs, plasticizers, antibiotics and biological macromolecules, showing its great potential in the field of separation and enrichment. Finally, the existing problems of RGO/Fe3O4 in research were put forward and the research and development orientation was briefly described.
