Graphene sheets (GS)@manganic manganous oxide (Mn 3 O 4 ) nanocomposites were prepared via a simple solvothermal process. [email protected] 3 O 4 /nafion (Nf) film modified glassy carbon electrode (GCE) was fabricated and applied for the detection of dopamine (DA) without the interference of ascorbic acid (AA) at the low working potential. The prepared nanocomposites ([email protected] 3 O 4 ) were characterized by X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FT-IR), and the morphology of different electrodes was charact...
