【Abstract】 Electrochemical behavior of p-nitrophenol on nano copper oxide electrode and its degradation were discussed. The effects of solution p H and thickness of material on electrochemical response of p-nitrophenol were examined. The results show that the difference( ΔE) of peak potential changed from 0. 862 V on bare GCE to 0.291 V on Cu O / PTH / GCE and the oxidation peak current increased obviously. Nano copper oxide could improve redox reversibility p-nitrophenol on electrode significantly. Electrochemical oxidation of p-nitrophenol was performed with nano Cu O / Ti electrode and electrolyte solution was tested by UV- visible spectra and high performance liquid chromatography,respectively. It illustrated the nano copper oxide could catalyze degradation of p-nitrophenol.更多还原
