摘要：

In this work, a new Fe3O4/graphene oxide (GO)/pristine graphene (PG) ternary composite (Fe3O4/GO/PG) was successfully synthesized. The structure of Fe3O4/GO/PG was characterized by transmission electron microscopy (TEM). The TEM result shows that the small PG sheets are attached to the larger GO sheets and the Fe3O4 nanoparticles are anchored on the surface of GO/PG composite. A sensor based on this Fe3O4/GO/PG has been fabricated successfully to detect dopamine (DA) and hydrogen peroxide (H2O2). The linear detection ranges for DA and H2O2 are 0.30-30 mu M and 0.50-277 mu M, respectively, with detection limits of 0.18 and 0.09 mu M.
