Different C-H Bond Activation Mechanisms on Solid Oxide Catalysts

Two different types of catalytic C-H bond activations in partial oxidations are discussed: (i) activation by transition metal oxides which exchange redox equivalents with the feed molecule (Mars-van Krevelen), and (ii) activation on metal oxides where redox equivalents are exchanged directly between a hydrocarbon molecule and a surface oxygen species.
For the former, we are particularly interested in support effects for vanadium oxide catalysts, in particular in the difference between reducible (VOx/CeO2)1 and non-reducible (VOx/SiO2) supports.2,3
For the latter, we discuss oxidative coupling of CH4 on (Li-)doped and undoped MgO surfaces.4
