| 中文摘要: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。 |

| Abstract:With the merits of high sensitivity，specificity，and analytical throughput，mass spectrometry has been recently applied to in-situ monitoring and mechanistic studies of electrochemical reaction 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 electrochemical 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 reviewed in three aspects：gas and volatile product analysis，liquid product analysis and short-lived intermediates identification．The applications of EC－MS in the monitoring of electrocatalytical systems and mechanistic studies of electrochemical reactions are also summarized． |
