Tungsten hexachloride is an important tungsten source for producing tungsten carbide composite catalytic material with platinum-like catalytic properties. For example, some researchers used tungsten hexachloride as the source of tungsten, the stripped montmorillonite sheet as the carrier, and combined the chemical impregnation method with the in-situ reduction carbonization technology to prepare tungsten carbide composite catalytic material - a nanocomposite of tungsten carbide and montmorillonite.

Wherein, tungsten carbide has platinum-like catalytic properties because its extranuclear electrons are similar to platinum, and it is used as a catalyst in the field of electrochemistry. Tungsten hexachloride is a blue-purple or dark blue fine-crystalline powder, which is one of the important raw materials for preparing new materials. The obtained tungsten carbide composite catalytic material is composed of tungsten carbide (WC), ditungsten carbide (W2C) and montmorillonite (MMT), and the tungsten carbide is dispersed in the form of particles or loaded on the outer surface of the MMT in layers.
