Mechanism of the catalytic action (IMAGE) Hokkaido University Caption Mechanism of the catalytic action. Platinum converts propane (C3H8) to form propylene (C3H6), while cobalt captures and activates CO2. When mixed together with indium and fixed on a cerium oxide support (CeO), the formation of propylene is linked to the deoxygenation of CO2, and is specific to propane. Water (H2O) and carbon oxides (COx) are formed as byproducts (Shinya Furukawa).
