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.

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。
