Patent

CA 2424269

A supported tungsten carbide material is provided. The material has a unique structure as defined by its x-ray diffraction pattern and consists of extremely small crystallites on the order of about 15 t about 30 angstroms in size. The tungsten carbide material is supported on a high-surface-area support to allow for a greater number of active sites for catalysis. The support consists preferably of a high-surface-area carbon.

L'invention concerne un matériau supporté à base carbure de tungstène. Ce matériau présente une structure unique définie par le diagramme de diffraction des rayons X et consiste en des cristallites extrêmement petites de l'ordre d'environ 15 à environ 30 angströms. Selon l'invention, le matériau à base carbure de tungstène est supporté par un support de surface active étendue afin de permettre à un plus grand nombre de sites actifs d'être catalysés. Le support consiste, de préférence, en un carbone de surface active étendue.
