| 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． |
