摘　　要：Aseries of ZnO-modified cobaltous ion exchanged ZSM-5 catalysts is prepared using incipient wetness impregnation and characterized by X-ray diffraction(XRD),N2 adsorption,transmission electron microscopy(TEM),UV-Vis diffuse reflectance spectroscopy(DR UV-Vis),X-ray photoelectron spectroscopy(XPS),pyridine-adsorbed Fourier transform infrared(Py-IR)and Raman.Their catalytic performance towards CO_(2)-assisted dehydrogenation of ethane to ethylene has been evaluated.The addition of ZnO onto CoZSM-5 obviously improved the yield of ethylene as well as the conversion of CO_(2).The promoting effect is attributed to the good activity of ZnO for the reverse water gas shift(RWGS)reaction,which enhances the coupling between RWGS and ethane dehydrogenation.
