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. |
