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.

通过循环伏安和计时电流法研究了该修饰电极对甲醇氧化的电催化活性和抗中间产物的毒化作用，并比较了该修饰电极与其单酸盐(Na2MoO4)修饰铂电极的性能，测试结果表明：磷钼酸修饰铂电极能够提高对甲醇氧化反应的催化活性，基本上同其单酸盐Na2MoO4修饰铂电极的催化活性相当，并且这种促进作用主要是由Mo原子价态变化引起的。

In order to disclosure the reason why the electrocatalysis activeness and selectivity droped after being used several hundred hours continuously, the x-ray diffraction, scanning electron microscopy and energy dispersive spectroscope have been used to characterize the surface condition variations of Monel metal. The results indicated: Monel metal belongs to the Cu-Ni alloy around the electrolysis experiment.And after being used for 600hr, the surface layer element composition and geometry distribution of the alloy changed, namely in the alloy the Cu element /which superficial free enthalpy was smaller,"concentrated" to the alloy surface,and formed one kind of marble structure microcrystallite.Thus the electrode surface becamed rough a

为了揭示蒙乃尔合金阴极在连续使用数百个小时后电催化活性剂选择性下降的原因，采用X射线衍射仪、电子扫描电镜和电子能谱分析仪对电解实验所用的蒙乃尔阴极材料在电解实验前后的表面状态进行了表征，结果表明：所使用的蒙乃尔合金阴极材料在电解实验前后均属于Cu-Ni合金，使用600hr后，由于表面层元素组成和几何排布发生了变化，即合金中表面自由焓较小的Cu元素向合金表面&富集&，形成一种大理石结构的微晶，表面粗糙、不均一，这是造成其对硝基苯电还原的催化活性及选择性随着使用时间延长而逐渐下降的主要原因，同时也为此类电极的修饰改进提供了方向。
