A reaction rate of methane conversion of 14.54 nmol -1 m -2 and the formation rate of aromatics of 2.22 nmol -1 m -2 at 973 K for the dehydrogenation and aromatization of methane in the absence of oxygen was attained over Mo-Ru/HZSM-5 catalysts. By comparison, over unpromoted Mo/HZSM-5 catalysts, th
Pulse reaction method and in situ IR spectroscopy were used to characterize the active oxygen species for oxidative coupling of methane (OCM) over SrF 2 /Nd 2 O 3 catalyst. It was found that OCM activity of the catalyst was very low in the absence of gas phase oxygen, which indicated that lattice ox
