Dehydrogenation of ethylbenzene and propane over Ga2O3–ZrO2 catalysts in the presence of CO2

Ga2O3–ZrO2 catalysts were prepared by a coprecipitation method. The catalysts were characterized by XRD, Raman, DRS, XPS, SEM, EDX, IR, NH3-TPD, CO2-TPD and N2 adsorption methods. Dehydrogenation of ethylbenzene and propane in the presence of CO2 over these catalysts has been investigated and compared. Ga2O3–ZrO2 catalysts exhibit different catalytic behavior for the two dehydrogenation reactions.
