【Abstract】 Combustion of fossil fuels provides more than 80% of the global energy supply nowadays. However, the rapid consumption of fossil fuels has raised great public concerns on energy sustainability and environmental security. Since chemical reactions play the crucial role in combustion and other thermal chemical processes in energy conversion, prior understanding of the chemical reaction mechanisms in these processes is essential for exploring new techniques to improve combustion efficiency and reduce pollutant emissions. This paper reviews our recent efforts in the development of new methods and instruments with synchrotron vacuum ultraviolet(VUV) photoioni- zation mass spectrometry and their applications in combustion and energy research, and presents perspectives of novel methods and applications in the near future.更多还原
