A novel MnO-CrN nanocomposite based non-enzymatic hydrogen peroxide sensor.

A MnO-CrN composite was obtained the ammonolysis of the low-cost nitride precursors Cr(NO)·9HO and Mn(NO)·4HO at 800 °C for 8 h using a sol-gel method. The specific surface area of the synthesized powder was measured BET analysis and it was found to be 262 m g. Regarding its application, the electrochemical sensing performance toward hydrogen peroxide (HO) was studied applying cyclic voltammetry (CV) and amperometry (-) analysis.
