| Abstract: | Polyoxometalate anion NaSb_9W_(21)O~(18-)_(86)(Sb_9W_(21))was firstly used as a modifier to fabricate a composite film modified glassy carbon electrode(GCE) by electrochemistry and layer-by-layer self-assembly methods.The electrochemical behavior of the Sb_9W_(21)-GCE was studied in acidic aqueous solution.The results show that the Sb_9W_(21)-GCE shows good electrocatalytic activity and good electrocatalytic activity toward the reduction of nitrite and bromate. |
