A mathematical model of simultaneous cobalt deposition and hydrogen evolution was developed and applied to the electroreduction process of 5 mM Co ions investigated by cyclic voltammetry (CV) technique at different hydrogen ion concentrations (pH=2, 3, 4). The kinetic parameters of such a complex process were determined, and the validity of the model and its sensitivity to changes in individual parameters were verified. The relative value of the approximate standard deviation (ASD ) was used to determine the degree of fit of the model to the experimental data. The catalytic effect of cobalt on the hydrogen evolution process was comprehensively confirmed.
建立了钴共沉积和析氢的数学模型，并将其应用于循环伏安（CV）技术在不同氢离子浓度（pH=2、3、4）下研究 5mM Co 离子的电化学还原过程。确定了这一复杂过程的动力学参数，并验证了模型的有效性及其对个别参数变化的敏感性。相对标准偏差（ASD）的相对值用于确定模型对实验数据的拟合程度。综合证实了钴对析氢过程的催化作用。
