| Abstract: | The electrochemical behavior of SiWnCo heteropolyacid in acidic aqueous solution was studied. The effect of solution pH on the electrochemical behavior of SiW11 Co was discussed. The modified electrode of SiW11Co heteropolyacid was made by adsorptive method. This modified electrode has good stability and electrocatalytic activity on the reduction of nitrite in acidic aqueous solution. |
