Abstract: Combustion provides over four fifths of the global energy supply, and is playing an irreplaceable role in energy, transportation, defense, industries, etc. Recognizing the crucial role of chemical reactions in combustion processes, research of combustion chemistry, especially development of kinetic models, enables us to better understand the combustion phenomena, control combustion behaviors and develop novel techniques for more efficient and cleaner combustion. In recent years, the applications of novel diagnostic tools like synchrotron vacuum ultraviolet (VUV) photoionization mass spectrometry in measurements of microscale combustion structure and the development of theoretical calculation methods have greatly improved the accuracy and applicability of kinetic models, contributing to the rapid development of combustion chemistry.In this paper,recent progresses in combustion chemistry research including theoretical calculations, experimental diagnostics and model development were reviewed,and perspectives of future work in this subject were presented.

Key words: microscale combustion structure, global combustion parameters, synchrotron VUV photoionization mass spectrometry, kinetic models, theoretical calculations
