摘　　要：当前,全球能源短缺、气候变化问题日益严重,开发和利用环境友好型能源迫在眉睫。质谱技术能够快速识别多组分物质、鉴定未知化合物结构,在光催化反应、电催化反应以及电化学储能装置开发等能源研究领域得到了广泛应用。本文介绍了液相色谱-质谱(LC-MS)、气相色谱-质谱(GC-MS)、基质辅助激光解吸电离质谱(MALDI-MS)、微分电化学质谱(DEMS)和电喷雾电离质谱(ESI-MS)等技术在反应瞬态中间体、产物检测和反应机理推测方面的应用,并对质谱技术在光催化降解、光催化合成、电催化还原、电催化合成、锂离子电池以及锂硫电池等领域面临的挑战和发展趋势进行展望。The development and utilization of environment-friendly energy is imminent with global energy shortage and climate change becoming increasingly serious.The advancement and utilization of environment-friendly energy,including photocatalytic hydrogen production,electrocatalytic pollutant removal,and the development of electrochemical energy storage devices,have emerged as prominent research topics.A variety of modern analysis techniques provide strong support in these related studies,such as X-ray absorption spectroscopy(XAS)for investigating the active site geometry and electronic structure of photocatalysts,synchrotron radiation X-ray photoelectron spectroscopy(SR-XPS)for real-time monitoring of interatomic electron excitation and transfer in photocatalysts,in situ electron paramagnetic resonance spectroscopy(EPR)for the detection of free radicals in photocatalysis reactions,Raman spectroscopy(RS)for analyzing the interfacial structure of electrochemical reactions,and in situ transmission electron microscopy(TEM)for studying catalyst structure and reactivity in photocatalytic reactions.While these techniques provide abundant information for the mechanistic aspects of the associated chemical processes,it remains challenging to conduct further identification and structural analysis of the reaction intermediates at a molecular level.Due to the ability in rapid identification of the components in complex system,mass spectrometry(MS)has been widely used in the new energy fields such as photocatalytic reaction,electrocatalytic reaction,and the development of electrochemical energy storage devices.This review introduced the application of mass spectrometry techniques,including liquid chromatography-mass spectrometry(LC-MS),gas chromatography-mass spectrometry(GC-MS),matrix-assisted laser desorption/ionization mass spectrometry(MALDI-MS),differential electrochemical mass spectrometry(DEMS),and electrospray ionization mass spectrometry(ESI-MS),in the detection of transient intermediates and products as well as the explora
