利用软模板结合电沉积法制备了一种有序化氰桥混配聚合物修饰铂电极（Nd-Fe-MoO₄^2-/Pt），用循环伏安法研究了在该化学修饰铂电极的丙三醇电催化氧化，并重点讨论了支持电解质的H⁺和SO₄^2-浓度、丙三醇浓度、扫速等因素对丙三醇电催化氧化活性的影响. 结果表明，在弱酸性硫酸钠支持电解质中，适当量SO₄^2-的存在有助于提高Nd-Fe-MoO₄^2-/Pt电极的丙三醇电催化氧化电流；-0.2 ~ 0.3 V电位区间内，其丙三醇氧化峰电流1与循环伏安曲线扫描速率的平方根之间呈现良好的线性关系，体现了扩散控制的反应特性；Nd-Fe-MoO₄^2-/Pt电极的丙三醇电催化氧化电流密度值约为裸铂电极的4倍，而丙三醇电催化氧化反应的表观活化能相对较小，修饰电极的电催化氧化呈现了明显的协同效应，其电催化氧化活性高、电流响应快、催化稳定性好.

A platinum electrode decorated with the ordered Nd-Fe-MoO₄^2- cyano-bridged mixed coordination polymer was successfully prepared by electrodeposition in virtue of the lyotropic liquid crystal soft template methods, and electrocatalytic oxidation behavior of glycerol was investigated on the chemically modified electrode by cyclic voltammetry. The influences of experimental factors such as the concentrations of H⁺ and SO₄^2- in electrolytes, glycerol concentration and scan rate on the electrocatalytic activity of glycerol at the modified electrode were also studied. It indicated that the proper amount of SO₄^2- in weakly acidic electrolyte could help to improve the electro-oxidation process of glycerol at the modified electrode. In the potential range of -0.2 ~ 0.3 V, the good linear relationship between the electro-oxidation current of glycerol (Peak 1) and the square root value of the scan rate revealed the fact that the electro-oxidation of glycerol had a diffusion-controlled characteristics. The oxidation peak current density of glycerol on the modified electrode was fourfold as large as that at the platinum electrode, while the apparent activation energy of the electrode reaction for glycerol had much less value. Therefore, there existed synergistic catalytic action to electro-oxidation process of glycerol at the Nd-Fe-MoO₄^2-/Pt electrode, and the modified electrode possessed the high electrocatalytic activity, fast current response and steady catalytic activity.
