The composition and the evolution of the 355 nm laser ablated plasma from a La2O3 target both in vacuum and in ambient O2 were investigated by using time - resolved emission spectrometry.

The results showed that (1) the surface area of supports increased; (2) theformation of spinel NiAl2O4 was inhibited by La2O3, CeO2 and MgO; (3) the surface activityof the nickel catalysts decreased, and (4)the activity of the nickel.

Partial oxidation of methane to syngas has been studied over NiO/Al2O3catalyst promoted with La2O3by using fixed-bed flow reactor.
