摘要：

Ordered mesoporous carbon (OMC) was successfully modified with one kind of electroactive inorganic compounds: Prussian blue (PB). The composites were characterized by Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, scanning electron microscopy (SEM) and electrochemical methods. The results show that, after depositing PB on the CIVIC, PB remains electroactivity. The new material obtained (PB/OMC) was used to modify glassy carbon electrode (CC). Compared with Prussian blue (PB) modified glassy carbon electrode (CC), the PB/OMC/GC electrode exhibits much better electrochemical stability, Much wider pH range and larger response currents to the reduction of hydrogen peroxide (H2O2). Additionally, the PB/OMC/GC electrode also exhibits remarkably strong and stable electrocatalytic response toward the oxidation of ascorbic acid (AA) compared with PB/OMC. (C) 2008 Elsevier Inc.
