We have developed a highly sensitive sensor of ZnFe2O4/reduced graphene oxide (ZnFe2O4/RGO) nanocomposite for electrochemical detection of hydrazine, fabricated by a simple hydrothermal protocol. Subsequently, a screen-printed electrode (SPE) surface was modified with the proposed nanocomposite (ZnFe2O4/RGO/SPE), and revealed an admirable electrocatalytic capacity for hydrazine oxidation. The ZnFe2O4/RGO/SPE sensor could selectively determine micromolar hydrazine concentrations. The as-produced sensor demonstrated excellent ability to detect hydrazine due to the synergistic impacts of the unique electrocatalytic capacity of ZnFe2O4 plus the potent physicochemical features of RGO such as manifold catalytic sites, great area-normalized edge-plane structures, high conductivity, and large surface area. The hydrazine detection using differential pulse voltammetry exhibited a broad linear dynamic range (0.03-610.0 µM) with a low limit of detection (0.01 µM).
