Tungsten disulfide

Tungsten disulfide is an inorganic <a href="/facts/Chemical_compound/37FXqqtv">chemical compound</a> composed of <a href="/facts/Tungsten/WYwbNDYX">tungsten</a> and <a href="/facts/Sulfur/IK0amTfM">sulfur</a> with the chemical formula WS2. This compound is part of the group of materials called the <a href="/facts/Chalcogenide/GTXXbDoV">transition metal dichalcogenides</a>. It occurs naturally as the rare mineral tungstenite. This material is a component of certain catalysts used for <a href="/facts/Hydrodesulfurization/CTXmxBQu">hydrodesulfurization</a> and <a href="/facts/Hydrodenitrification/1fFrSaYH">hydrodenitrification</a>.
WS2 adopts a layered structure similar, or <a href="/facts/Isostructural/xWlgsQ95">isotypic</a> with <a href="/facts/Molybdenum_disulfide/4TRft6Ua">MoS2</a>, instead with W atoms situated in trigonal prismatic <a href="/facts/Coordination_sphere/s3vUKWjp">coordination sphere</a> (in place of Mo atoms). Owing to this layered structure, WS2 forms <a href="/facts/Non-carbon_nanotube/lJoWBCeV">non-carbon nanotubes</a>, which were discovered after heating a thin sample of WS2 in 1992.
