Synthesis of Palladium, ZnFe₂O₄ Functionalized Reduced Graphene Oxide Nanocomposites as H₂O₂ Detector

In the present work, a highly efficient catalyst toward the reduction of hydrogen peroxide (H₂O₂) was synthesized on account of reduced graphene oxide (rGO). The rGO were coated with ZnFe₂O₄ and Pd nanoparticles (Pd/ZnFe₂O₄/rGO), which were used to modify a glassy carbon electrode to detect H₂O₂. The Pd/ZnFe₂O₄/rGO nanocomposites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray powder diffraction, and X-ray photoelectron spectroscopy. Cyclic voltammetry and amperometry measurements were used to characterize and optimize the property of as-prepared H₂O₂ sensor. The proposed H₂O₂ sensor displayed a wide linear range from 25 μM to 10.2 mM with an enhanced sensitivity of 621.64 μA mM^–1 cm^–2
