| Abstract: | A new bimetallic oxycarbide was synthesized and characterized by XRD, TEM, EDS, XPS and adsorption–desorption of probe molecules.
All the molybdenum was reduced and 35% of tungsten was present as WOx. The number of metallic sites, Lewis and Br?nsted acid sites were estimated. A turnover rate of 0.1 s−1 was measured at 300 °C for the first order n-heptane isomerization. |
