Non-enzymatic electrochemical sensors for the detection of H2O2 based on Mn3O4 octahedron submicrostructures

Abstract	In this reported work, Mn3O4 octahedron submicrostructures (Mn3O4 OSMs) were obtained through a facile solvothermal method in mixed solvent. The authors have modified a glassy carbon electrode (GCE) with Mn3O4 OSMs and Nafion to obtain a sensing platform (Mn3O4 OSMs/Nafion/GCE) for the non-enzymatic detection of H2O2. The resulting Mn3O4 OSMs/Nafion/GCE exhibited good electrochemical catalytic activity towards the reduction of H2O2 in a phosphate buffered solution (0.1 M, pH = 7.0). The linear detection range was estimated to be in the range from 5 µM to 17 mM (R = 0.9998), and the detection limit was estimated to be 1.5 µM at S/N = 3. Real sample analyses show that the sensor developed in this work could be efficiently used for the determination of H2O2.
