摘　　要：质谱分析法以其灵敏度高、特异性强、分析通量高等特点,近年来已逐步用于电化学反应过程的原位监测和机理探究。通过开发新型电离源以及构建电化学池-质谱偶联装置,研究者们相继发展了一系列电化学质谱(EC-MS)分析方法,并在电化学过程产物实时监测、同位素标记分析、短寿命中间体捕获鉴定等方面展现出了特有的技术优势。该综述从气相及挥发性产物分析、液相产物分析和短寿命中间体捕获三方面介绍了EC-MS近五年来在方法学方面的研究进展,并回顾了这期间EC-MS在电催化过程产物监测和电化学反应机理研究中的应用。With the merits of high sensitivity,specificity,and analytical throughput,mass spec⁃trometry has been recently applied to in-situ monitoring and mechanistic studies of electrochemical re⁃action processes.In the past decades,a series of electrochemical mass spectrometry(EC-MS)analysis methods have been developed by advancing novel ionization sources and interfacing electro⁃chemical cell with mass spectrometers,which have exhibited excellent performance in the real-time monitoring of electrochemical processes,isotope labeling analysis,capture short-lived intermediates and other aspects.In this review,the methodological progress of EC-MS in the past five years is re⁃viewed in three aspects:gas and volatile product analysis,liquid product analysis and short-lived in⁃termediates identification.The applications of EC-MS in the monitoring of electrocatalytical sys⁃tems and mechanistic studies of electrochemical reactions are also summarized.
