摘　　要：燃烧是当今世界的主要能源来源,在交通运输、工业生产和航空航天等领域发挥着重要的作用。燃烧过程伴随着污染物的产生,带来严重的环境问题。为了提高燃烧效率、降低污染物排放,我们需要理解并认识燃烧,最终可以控制燃烧。中间产物是燃烧反应网络的链载体,对关键中间产物定性和定量测量是认识燃烧的重要环节,也是发展和验证燃烧反应动力学模型的重要基础。另一方面,各种化学品和燃料的制备均涉及催化过程,对于催化反应中间产物的检测,可以进一步揭示催化反应机理,并定向调控催化反应路径,提高目标产物的转化率。上述关键中间产物,尤其是活泼中间产物的检测一直是测量的难点。近年来,我们发展的同步辐射真空紫外光电离质谱技术,结合超声分子束取样,可以检测燃烧及催化反应过程中的关键中间产物,如烯醇、过氧化物、自由基等。本文详细介绍了同步辐射真空紫外光电离质谱技术及其在燃烧和催化研究中的应用,并展望未来的发展方向。Combustion is the main energy source in the world,and plays an important role in the fields of transportation,industrial production,aerospace,etc.The combustion process is accompanied by the production of pollutants,which lead to serious environmental problems.In order to improve combustion efficiency and reduce pollutant emissions,it is necessary to understand and control combustion.As intermediates are the chain nodes of combustion reaction network,qualitative and quantitative measurements of key intermediates are essential not only for understanding combustion,but also for developing and verifying combustion reaction kinetic models.On the other hand,the preparation of various chemicals and fuels involves catalytic processes.The detection of catalytic reaction intermediates can further reveal the catalytic reaction mechanism,regulate the catalytic reactions and improve the conversion of target products.The detection of these key intermediates,especially active intermediates,has always been challenging.In recent years,the synchrotron radiation vacuum ultraviolet photoionization mass spectrometry(SVUV PIMS)combined with molecular beam sampling,can detect the key intermediates in the process of combustion and catalytic reaction,such as enols,hydroperoxides,free radicals,etc.Herein,SVUV PIMS and its application in combustion and catalysis were summarized in detail,and the future development direction was prospected.
