Calcium-nickel oxides doped with potassium are good catalysts for the oxidative coupling of methane. Their catalytic activity depends on the concentration and distribution of the potassium throughout the calcium nickel oxide matrix. Thin films of calcium-nickel-potassium oxides have been made using pulsed laser deposition. The normalized percentage of potassium in the films was as high as 42% and as low as 7%, as shown by energy dispersive X-ray spectroscopy (EDX). X-ray diffraction studies of the films reveal that the potassium doped into the calcium-nickel oxide forms a phase that has been previously unidentified.
