We are interested in catalysts consisting either of substitutionally doped oxides (e.g. RuxCe1-xO2) or of submonolayers of an oxide supported on another oxide (e.g. VOx supported on ceria). Calculations and experiments show that in most cases these systems are more active catalysts than the original oxide (i.e. ceria). We use theory to try to find general patterns governing the activation by do...

Methane reforming allows the production of synthesis gas (syngas) which is an important mixture feedstock for chemicals and energy carriers. Steam methane (SRM) partial oxidation (POM) have been deployed at large industrial scale, while dry (DRM) more recently tri-reforming (TRM) are intensively studied. TRM simultaneously combines SRM, POM DRM in a unique process overcoming several weaknesses ...
