石墨烯负载铁酸锌纳米材料的制备及应用

In this paper, ZnFe2O4/rGO nanocompositewas synthesized by solvothermal method and modified on the surface of glassy carbon electrode. The electrochemical performance was tested. The large specific surface area of graphene and the porous structure of zinc ferrite promote the reduction of H2O2 to a certain extent. The aim of the experiment was to optimize the experimental conditions to study the electrocatalytic activity of H2O2. The composites were characterized by SEM, TEM, XRD and XPS. The synergistic effect between graphene and ZnFe2O4 further improves the catalytic activity. The preparation method of the modified electrode is simple, environmentally friendly, fast, and has good reproducibility and stability. It is applied to the H2O2 detection system to realize the quantitative detection of H2O2.
