Dimethylamine borane (DMAB) is a promising fuel alternative for fuel cell applications. In this work cyclic voltammetric behavior of DMAB was investigated on the polymerized aminophenol film decorated with Ag nanoparticles in alkaline media. The polymer film was formed on the glassy carbon electrode by electrochemical technique and then, the surface was modified with Ag nanoparticles. The surface of the modified electrode was identified by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and electrochemical impedance spectroscopy techniques. The developed electrode has displayed high electrocatalytic activity for DMAB oxidation in alkaline media depending on the supporting electrolyte concentration. Experimental parameters such as cycle number used in electropolymerization of p-aminophenol, deposition of Ag nanoparticles and supporting electrolyte were optimized.
二甲胺硼烷（DMAB）是一种很有前景的用于燃料电池的替代燃料。在这项工作中，研究了在碱性介质中，二甲胺硼烷在装饰有银纳米颗粒的聚合氨基酚薄膜上的循环伏安行为。通过电化学技术在玻碳电极上形成聚合物薄膜，然后用银纳米颗粒对表面进行修饰。通过扫描电子显微镜、透射电子显微镜、X射线光电子能谱和电化学阻抗谱技术对修饰电极的表面进行了鉴定。所开发的电极在碱性介质中对二甲胺硼烷氧化表现出高电催化活性，这取决于支持电解质的浓度。对诸如对氨基酚电聚合中使用的循环次数、银纳米颗粒的沉积和支持电解质等实验参数进行了优化。
