Highly sensitive non-enzymatic hydrogen peroxide sensor based on manganese dioxide nanocomposite
This paper describes the fabrication of a non-enzymatic Hydrogen peroxide (H2O2) based on the use of MnO2 ultralong nanowire, CNT and chitosan. A MnO2-CNT-CHI composite was created and dropped onto the surface of a glassy carbon electrode. The electrochemical behaviors of H2O2 at the modified electr...

| description | This paper describes the fabrication of a non-enzymatic Hydrogen peroxide (H2O2) based on the use of MnO2 ultralong nanowire, CNT and chitosan. A MnO2-CNT-CHI composite was created and dropped onto the surface of a glassy carbon electrode. The electrochemical behaviors of H2O2 at the modified electrode were investigated by cyclic voltammetry and amperometry. The results showed that the MnO2-CNT-CHI composite acted as an excellent catalyst in H2O2 electrochemical reactions, with a linear response in the concentration range of H2O2 from 0.99 μM to 247μM, and a limit of detection at 15 μM. The advantages of the proposed sensor such as the low detection limit and wide linear range indicates that it is a promising electrochemical platform for H2O2 detection. |
