The activation of [MoX3(L)] (with X = Cl, Br; L = tridentate ligands with S3 and SNS donor sets) by AlMe3, analogous to the industrially important [CrCl3(L)] catalysts for selective oligomerisation of alkenes, has been investigated by X-ray absorption (XAS) and UV-visible spectroscopies. Time-resolved stopped flow XAS, as developed by our group for homogeneous catalysis over the last few...

The number of publications reporting the application of gold to catalytic processes has increased dramatically since the discovery in the 1980’s that supported nanoparticles of gold can be very active catalysts for industrially important reactions [1,2]. Despite the tremendous progress in the field in terms of catalyzed reactions, understanding of the catalytic behaviour of heterogeneous gold...

The catalytic activity of catalysts is commonly guided by the interplay of geometric and electronic effects at the active center. It are the highest occupied (HOMO) and lowest unoccupied (LUMO) states that interact with the substrate in dependence of the coordination geometry. Knowledge about these three “structure factors” is therefore a key to understand catalytic mechanisms and the working...

Methanol steam reforming (MSR) is a promising reaction for H2 production for use in PEM fuel cells. In contrast to Pd on inert support oxides, which catalyzes methanol decomposition to CO and H2, Pd supported on ZnO and Ga2O3 has shown excellent activity and selectivity to the steam reforming reaction yielding H2 and CO2 [1]. Based on ex-situ characterization after reaction or reduction, this...

In the last decade, Groothaert et al. showed that methane can be converted to a methanol-like species at mild conditions using Cu-exchanged zeolites [1]. However, the product strongly sorbed to the surface and the process was not catalytic. To successfully activate methane by partially oxidation to a methanol derivative one must understand the reaction mechanism. This necessitates knowing the...

LaFe0.95Pd0.05O3 is currently used as a component of automotive three-way catalysis for the emission control of stoichiometric gasoline engines. It is known that LaFe0.95Pd0.05O3 is able to segregate metallic palladium to its surface when reduced and to re-incorporate it to form a solid solution when re-oxidized, which is described as the self-regenerative function [1]. Catalytic activity...
