Carbon dioxide (CO2) assisted oxidative dehydrogenation of propane over Ga-modified catalysts is highly sensitive to the identity support, but underlying cause support effects has not been well established. In this article, SSZ-13, SSZ-39, ZSM-5, silica and γ-Al2O3 were used load Ga species by incipient wet impregnation. The structure, textural properties, acidity Ga-based process CO2-assisted ...
