Also the performance of this modified electrode was compared with sodium molybdate modified platinum electrode. The cyclic voltammetry tests show that phosphomolybdic acid modified platinum electrode can increase the catalytic activity for methanol oxidation and it is almost the same as the mono-molybdate (Na2MoO4) modified Pt electrode does. This promote effect mainly comes from the transformation of different valency of molybdenum.
