In the oxidative dehydrogenation of propane in the presence of CO2, supported monometallic M/SiO2 (M = Zn, Cu) and bimetallic MCr/SiO2 oxide catalytic systems were studied in the temperature range 600–700°C. The catalytic systems were characterized by TG–DTG–DTA, SEM–EDX, and UV–Vis diffuse reflectance spectroscopy. It was revealed that the addition of a second metal leads to a decrease in propane conversion to 32%, while the selectivity for propylene increases to 75% on the 3Zn3Cr/SiO2 sample at 600°C.
