Fabrication and electrochemical behavior of multilayer films containing 1 : 12 phosphomolybdic anions and their electrocatalytic oxidation of ascorbic acid
A novel kind of multilayer film containing 1:12 phosphomolybdic anions was achieved on the surface of gold electrode by alternate deposition of 1:12 phosphomolybdic anions with water-soluble bipolar pyridine salt (PyC6BPC6Py). The electrochemical behavior of the multilayer films was described. The catalytic effect of the multilayer films on the oxidation of ascorbic acid was studied.
