Received Date: 28 July 1994

The dioxygen species was characterized and their thermostability was investigated on BaF₂-LaOF catalyst by means of in situ Raman spectroscopy in the temperature range of 298K to 1023K.It is found that there exist mainly the O₂ ^2-ions and a little amount of O₂^2-(1 < n < 1)ions at the temperature for OCM(1023K)on BaF₂-LaOF catalyst in O₂ stream.These dioxygen species can be expected to be the active sites for OCM.
