Herein, we report a simple hydrothermal synthesized V2O5 flake employed as an electrode material for non-enzymatic hydrogen peroxide (H2O2) sensor application. The morphology, structural, and electrochemical properties of the as-prepared material were characterized by using various physicochemical and electrochemical methods viz. scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and amperometric (i-t). Moreover, an excellent electrochemical performance has been achieved by using the V2O5 flakes modified glassy carbon electrode (GCE) over the reduction of H2O2. In optimum experimental conditions, the reported electrochemical sensor was found with a wide linear range (0.1–408 μM), low detection limit (0.06 μM), and excellent sensitivity (9.87 μA μM−1 cm−2) with anticipated selectivity. Hence, the novel as-prepared V2O5-GCE provides a new avenue for the fabrication of amperometric H2O2 sensor with excellent real sample analysis. [Figure not available: see fulltext.].
