摘要：
A series 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 CO2-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 CO2. 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.
