Obtaining tungsten carbides from tungsten bipyridine complexes via low temperature thermal treatment
Tungsten carbides were prepared by thermal treatment under nitrogen of a tungsten bipyridine complex. The catalysts obtained have been characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), temperature programmed reduction (TPR) and elemental analysis. The reaction with 2-methylpentane was used as a chemical probe for the formation of tungsten carbide.
