| Abstract: | Several analytic methods, such as XPS, XRD, EXAFS and EHMO quantum calculation were used to verify that oxygen atoms are inserted in the lattice of tungsten carbide prepared at low temperature. Just like Pt, tungsten carbides have catalytic activities for hydrocarbon conversion and carbon monooxide hydrogenation. Oxygens in the lattice lower the specific catalytic activity of tungsten carbide for these reactions. |
