Abstract: The composition a nd structure of La-Th-O mixed oxides as well as their catalyticactivity for methane oxidative coupling have been studied by means of XRD,XPS and IR.The results indicated that the solid solution of LaxTh1-xO2-δ with the fluorite structure wasformed in the range 0≤x≤0.6,and it was the main active phase for oxidative coupling of methane.

Key words: methane, oxidative coupling, catalyst, lanthanum thorium oxide
