Identification of active oxygen species for soot combustion on LaMn03 perovskitef

摘要

Active oxygen species for soot combustion with O2 on LaMnO3 were identified as O_2~(2-), O_2~(n-) (1 < n < 2) and O_2~(m-) (0 < m < 1) for the first time using in situ Raman spectroscopy during temperature-programmed oxidation (TPO) from room temperature to higher temperatures.
