电化学合成氨LSV、CV曲线

线性扫描伏安法是在电极上施加一个线性变化的电压，即电极电位是随外加电压线性变化记录工作电极上的电解电流的方法。记录的电流随电极电位变化的曲线称为线性扫描伏安图。循环伏安法是一种简单而强大的研究方法。通过循环的伏安法，可以对电极可逆性进行判断：反应是可逆的，则曲线上下对称，若反应不可逆，则曲线上下不对称。随着扫描速度的增加，峰电流也增加。且分别测量他们的峰数据可以得到峰电流与扫描速度的关系。在对于电催化合成氨体系中进行LSV/CV曲线测试时可以直观了解到催化剂的活性、反应时否可逆以及催化剂的循环稳定性，以便对催化剂进行后续的改进。

Linear Sweep Voltammetry (LSV) is an electrochemical technique that applies a linearly ramped voltage to the working electrode, and records the electrolytic current generated at the working electrode as the electrode potential changes linearly with the applied external voltage. The curve depicting the variation of the recorded current with electrode potential is termed a linear sweep voltammogram. Cyclic Voltammetry (CV) is a simple yet powerful research method. Using cyclic voltammetry, the reversibility of an electrode reaction can be assessed: if the reaction is reversible, the resulting voltammogram is top-bottom symmetric; if the reaction is irreversible, the voltammogram will be asymmetric. As the scan rate increases, the peak current also increases. By separately measuring the peak parameters, the relationship between peak current and scan rate can be derived. When conducting LSV and CV tests on an electrochemical ammonia synthesis system, researchers can intuitively obtain insights into the catalyst’s activity, the reversibility of the reaction, and the cyclic stability of the catalyst, thereby guiding subsequent improvements to the catalyst.
