Tungsten Disulfide Catalysts

There are three main types of tungsten disulfide catalysts that have high chemical activity. They are hydrogenation active catalyst, non-polar functional material catalyst and photocatalyst. Tungsten Disulfide Catalysts have high application value in petroleum industry and other important fields.

Tungsten disulfide has a special layered structure inside. The surface and exposed edge of the lamellar has high chemical activity that chemical reactions occur easily. So tungsten disulfide is often used as an efficient catalyst.

There are three main types of tungsten disulfide catalysts:

1. Hydrogenation Active Catalyst

Hydrogenation active catalyst is suitable for desulfurization, denitrification and dearomatization of petroleum, which is beneficial to the production of environmental protection in petroleum industry. In order to develop the catalyst with ultra-high hydrogenation activity, the unsupported catalyst came into being. At present, the main non-supported catalysts are the hydrogen desulfurization catalysts with tungsten disulfide and molybdenum disulfide as carriers and CO and Ni as auxiliary agents. Tungsten disulfide mainly plays the role of bearing active components, increasing the dispersion of active components and auxiliaries in catalyst. Unsupported catalyst tungsten disulfide has the advantages of high cracking performance, stable and reliable catalyst performance, long catalytic life, etc.

2. Inorganic Functional Materials Catalyst

Tungsten disulfide is an excellent catalyst for the preparation of inorganic functional materials. Two-dimensional nanomaterials with a single molecular layer can be rearranged and stacked according to people's needs to form new materials with internal space. Meanwhile, in the process of rearrangement and combination, other elements or substances can be added between layers or inside particles to obtain composite catalysts or superconducting materials.

3. Photocatalyst

Due to its light weight and large specific surface area, nanometer tungsten disulfide has also been used in photochemical catalysis. At present, many studies show that, under appropriate lighting conditions, many organic compounds are degraded into some simple inorganic substances such as non-toxic CO₂ and H₂O under the action of tungsten disulfide photocatalyst.
