Electrocatalysts have received enormous attention for use in applications related to the electrochemical sensing of hydrogen peroxide (H2O2). In this work, we synthesized a graphite-like carbon nitride (g-C3N4)/reduced graphene oxide (rGO) composite (g-C3N4/rGO) using a hydrothermal approach and characterized it by powder Xray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive electron microscopy, and X-ray photoelectron spectroscopy. The synthesized material (g-C3N4/rGO) was deposited on a screen-printed carbon electrode (SPE) to investigate its performance as an H(2)O(2 & nbsp;)sensor. Cyclic voltammetry (CV) and linear sweep voltammetry (LSV) were adopted to evaluate the H2O2 detection properties of the g-C3N4/rGO composite-modified SPE (g-C3N4/rGO/SPE). The g-C3N4/rGO composite material exhibited excellent H2O2 detection ability with a detection limit as low as 0.09 mu M and sensitivity of 10.34 mu A/mu Mcm(2) using LSV. The C3N4/rGO/SPE also showed good selectivity, stability and excellent repeatability for H2O2 detection. These properties make the fabricated material an ideal candidate for practical applications that may be explored in future research.
