Title: Preparation of CNT/nano-TiO_2 Modified Electrode and Its Heterogeneous Electrocatalytic Performance
Abstract: Complex sol of CNT/nano-TiO2 was prepared by sol-gel method.The sol was coated on Ti matris to obtain a novel complex CNT/nano-TiO2 modified electrode(C electrode).The electrochemical properties of C electrode were investigated by cyclic voltammetry,chronocoulometry and EIS.The results showed that CNT can block congregation of nano-TiO2 particle,the current values of the second redox peaks of C electrode were about twice higher than that of pure nano-TiO2 modified electrode(P electrode) in cyclic voltammograms.C electrode exhibited higher electrocatalytic activity than P electrode in heterogeneous electrocatalytic reaction in oxalic acid solution,and higher reduction ability to hydrogen peroxide.
