Abstract


  • Hematite nanoparticles (α-Fe2O3) are successfully decorated on the reduced graphene oxide (rGO) sheets through a simple, one-step, hydrothermal method without addition of other reducing agents. The α-Fe2O3/rGO hybrid was characterized by scanning electron micrographs, X-ray diffraction, X-ray photoelectron spectroscopy, and Raman spectroscopy. This α-Fe2O3/rGO hybrid has been successfully applied in the catalytic performance toward the reduction of H2O2. The nonenzymatic sensor demonstrates a linear relationship over a wide concentration range of 5.0–4495.0 μM (R = 0.9998), a low detection limit of 1.0 μM, and a high sensitivity of 126.9 μA cm−2 mM−1 to the detection of H2O2.
