摘要：
A Cu2O/Cu electrode was fabricated by applying an anodic voltage to the Cu electrode in a mixed alcohol-water solution containing 1,3,5-benzentricarboxylic acid and NaClO4. The Cu2O/Cu electrode was characterized by scanning electron microscopy, X-ray powder diffraction and electrochemical technique. The results showed that ultrafine Cu2O microcrystal was densely assembled on the Cu electrode and as-prepared Cu2O/Cu electrode exhibits large surface area. The resulted sensor showed high catalytic activity towards the oxidation of glucose with a wide linear range of 0.05-6.75 mM and detection limit of 37 mu M. The good catalytic activity, high sensitivity and good stability made such Cu2O/Cu electrode to be a promising candidate for constructing novel enzyme-free sensor.
