选用Cu-Zn合金作工作电极,以KHCO3水溶液作电解液,研究常温常压下CO2和NO3-同步电化学还原合成尿素的电极过程,通过对循环伏安曲线及产物分析,初步建立“三元竞争”模型,该模型能解释本实验研究范围内电极过程的基本情况,可以为后续研究起参考作用。
Cu-Zn alloy was selected as the working electrode and KHCO3 aqueous solution was used as the electrolyte to study the electrodeposition process of CO2 and NO3-synchrochemical synthesis of urea under normal temperature and pressure. Through the analysis of cyclic voltammetry and product analysis, Yuan competition "model, the model can explain the basic situation of the electrode process within the scope of this experiment can serve as a reference for subsequent studies.
