I-Tungsten disulfide (WS2) ngobuninzi isetyenziswe iminyaka emininzi njenge-lubricant eyomileyo ngenxa yendlela ebonisa ngayo iimpawu ze-coefficient ephantsi ye-friction, ukuzinza okuphezulu kweekhemikhali, kunye nokuzinza kwe-thermal. Ngo-1992, kwafunyaniswa ukuba ulwakhiwo lwe-WS2 luyenze ikwazi ukwenza izakhiwo ze-nanotube. Ezi nanotubes yayiyimizekelo yokuqala ye-WS2 esetyenziswa njengento ephantsi-dimensional. Emva kokufunyanwa kweendlela ezilula zokukhupha ii-mechanical exfoliation zokwahlula iileya zodwa ze-2-D materials, kwakunokwenzeka ukufunda iipropathi ze-WS2 flakes. Kwaboniswa ukuba, njenge-MoS2, i-band-gap ye-WS2 iyatshintsha ukusuka kwi-indirect band-gap ye-1.4eV ukuya kwi-band-gap ethe ngqo ye-2eV xa utshintsha ukusuka kwizinto ezininzi ukuya kwi-2-D. Ngenxa ye-band-gap, i-WS2 ibonwa njengento enomdla kakhulu kwiindawo ezininzi zokusetyenziswa. I-WS2 inomlinganiselo ophezulu wokuvula/ukucima kwii-transistors ze-field-effect, i-spin elawulekayo kunye ne-valley polarisation, uvalelo olomeleleyo lwejometri yee-excitons, kunye ne-photoluminescence enokutyibilikayo. Ukongezelela, i-WS2 inokukhokelela ekwandeni komdla kwiindawo ezifana ne-photodetectors kunye ne-multi-junction photovoltaics. Ngaphandle koko, i-WS2 isetyenziswa, ngokudibeneyo nezinye izinto, njenge-catalyst ye-hydrotreating ye-oyile ekrwada. ILamellar tungsten disulfide isetyenziswa njengesithambiso esomileyo kwiziqhoboshi, iibheringi, kunye nokubumba phantsi kwegama elithi Dicronite. I-Tungsten disulfide (WS2) isetyenziswa njengesithambiso esiqinileyo esikwaziyo ukumelana namaqondo obushushu aphezulu. Ikwasetyenziswa njengesithambiso sokutshiza. I-Tungsten sulfide isetyenziswa njengenxalenye ye-catalysts ye-hydrotreating yeoli ekrwada, i-hydrodesulfurization kunye ne-hydrodenitrification reactions. Ifumana isicelo njenge-cathodes yebhetri ye-lithium yesibini kunye nezinye izixhobo ze-electrochemical. Kufunyaniswa ukuba yenza i-nanotubes ye-inorganic, eyona nto ingcono yokuqinisa i-agent kune-carbon nanotubes. Ukongezwa kwe-tungsten sulfide kwi-epoxy resin iphucula ukunamathela, ukuqina kokuqina kunye noxinzelelo lwesantya sokukhutshwa kwamandla. I-Tungsten sulfide ine-pseudo 2 dimensional structure kunye nezicelo kwishishini lePetrochemical njenge-catalyst ye-desulfurization. I-Tungsten Sulfide nanoparticles itsale umdla wophando ngenxa yesakhono sazo kwizithambisi eziqinileyo zelizwe; iingubo kunye neefotocatalysts.
