Preparation of vanadium-titanium acid-polyaniline film modified electrode and electrochemical properties
With aniline and self-made vanadium-titanium acid as raw materials,ITO conductive glass as basal electrode,the vanadium-titanium acid-PANI films modified electrodes is prepared by one-step and two-step methods.The mechanism and electrochemical behavior of the composite films are investigated systematically.The results show that the preparation process of one-step is simple,and vanadium-titanium acid fix in the PAn thin films layer by layer.The modified electrodes not only maintain the electrochemical and electrocatalytic properties of vanadium-titanium acid,but also have good stability.The modified electrodes show high catalytic activity towards the iodate ions in acidic aqueous solution.
