Methane transformation over Ni and Cu modified Sr2+/La2O3 catalysts has bee
n studied. These species favor formation of reducible mixed oxides and chan
ge the surface reactivity of the Sr2+/La2O3 system, modifying the reaction
mechanism since Sr2+/La2O3 favors methane oxidative coupling but with coppe
r methane combustion is favored and nickel favors partial oxidation.
