Recently high quality structures have become available for the M1 and M2 phases of the MoVNbTeO multi-metal oxide (MMO) catalysts capable of selectively activating propane to form acrylonitrile and other important monomers for modern polymer materials. However the details of the chemical mechanisms controlling selectivity and activity have remained elusive because important sites in these structures...
Activation of non reactive C H bonds and their transformation into C OH alcohol groups without the occurrence of significant further oxidation to aldehydes or acids is one of the reasons that methane mono-oxygenase (MMO) stands out as an interesting example of a di-iron containing enzyme. The di-iron site in MMO catalyzes the dissocciative binding of molecular oxygen. To mimic the MMO active site...
