A novel material based on cupric(II) oxide/macroporous carbon and its enhanced electrochemical property

A novel material based on cupric(II) oxide/macroporous carbon nanocomposites (CuO/MPC) has been prepared through a simple hydrothermal process. In the process of synthesis, the incorporation of MPC leads to a well-dispersed CuO nanoneedles on the surface of MPC. The new composite material combined the unique property of CuO and MPC, showed improved electrochemical activity towards H2O2 reduction and glucose oxidation. Based on the improved electrochemical property of CuO/MPC modified electrode, it can be used as sensor for the determination of H2O2 and glucose. In addition, the CuO/MPC modified electrode displayed good stability and antifouling features towards glucose oxidation. These results also indicate that CuO/MPC nanocomposites have of wide application foreground. (C) 2011 Elsevier Ltd. All rights reserved.
