Tungsten Sulfide(WS2): Mashandiro uye Mashandisirwo

WS2, inozivikanwawo se tungsten sulfide igrey, hexagonal system, semiconductor uye diamagnetic. Ine friction coefficient yakaderera kwazvo (0.03), high extreme pressure resistance uye oxidation resistance (kuora kunotanga pa450 ℃ mumhepo, Yakakodzera tembiricha yakakwira, high pressure, high vacuum, high load, high speed, high radiation, strong corrosion, ultra-low tembiricha nedzimwe mamiriro akaomarara.

WS2 / tungsten sulfides / tungsten disulfides / tungsten (IV)Sulfide chinhu chave chichinyanya kufarirwa munharaunda yesainzi nekuda kwehunhu hwayo hwakasiyana uye mashandisirwo ayo anogona kuitwa. Muchinyorwa chino, tichaongorora kuti WS2 chii, hunhu hwayo, uye mashandisirwo ayo anogona kuitwa muminda yakasiyana-siyana.

WS2imusanganiswa unoumbwa nemaatomu etungsten nesarufa, ane fomura yemakemikari yeW(S2). Ndewemhuri ye transition metal dichalcogenides (TMDs), ayo ari zvinhu zvakarongwa zvine chimiro chakafanana negraphene. WS2 ine chimiro chakarongwa chine maatomu etungsten akarongwa pakati pezvikamu zvemaatomu esarufa. WS2 inoshandisa chimiro chakarongwa chine chekuita neMoS2(Molybdenum Disulfide), ine maatomu eW ari muchikamu chetrigonal prismatic coordinate sphere, Chimiro ichi chine layer chinopa WS2 hunhu hwayo hwakasiyana uye chinoita kuti ive chinhu chinonakidza chekutsvaga kwesainzi uye mashandisirwo etekinoroji.

Chimwe chezvinhu zvinonyanya kuzivikanwa zveWS2ndiyo hunhu hwayo hwekuzora. WS2 ine coefficient yakaderera yekukweshana, izvo zvinoita kuti ive mafuta akanaka kwazvo ekushandisa kwakasiyana-siyana. Yakashandiswa semafuta akasimba munzvimbo dzinopisa zvakanyanya uye dzine kumanikidzwa kwakanyanya, senge muindasitiri yendege nemotokari. Maumbirwo eWS2 ane zvidimbu zvinoita kuti itsvedzerere pamusoro peimwe neimwe zviri nyore, zvichideredza kukweshana uye kupfeka pakati penzvimbo.

Kuwedzera pahunhu hwayo hwekuzora mafuta,WS2inoratidzawo maitiro e semiconducting. Izvi zvinoreva kuti inogona kushandiswa mumidziyo yemagetsi uye mashandisirwo e optoelectronic. WS2 yakaratidza mukana wekushandiswa muma transistors, photodetectors, uye solar cells nekuda kwehunhu hwayo hwemagetsi hwakasiyana. Kukwanisa kwayo kupinza nekuburitsa chiedza zvinobudirira kunoita kuti ive chinhu chinovimbisa kune michina ye optoelectronic yechizvarwa chinotevera.

Uyezve,WS2yakaongororwa kuti inogona kushandiswa sei mu catalysis uye kuchengetedza simba. Nzvimbo yayo yepamusoro uye mashandiro ayo anoita kuti ive chinhu chinobatsira pakushandiswa mumasero emafuta, hydrogen evolution reactions, uye mamwe maitiro e catalytic. Zvinhu zvakagadzirwa neWS2 zvakaongororwawo kuti zvinogona kushandiswa mumidziyo yekuchengetedza simba, senge mabhatiri nema supercapacitors, nekuda kwe conductivity yayo yepamusoro uye electrochemical properties.

Hunhu hwakasiyana hweWS2zvakakwezvawo kufarira mumunda we nanotechnology. WS2 nanoparticles uye nanosheets zvakagadzirwa uye zvakadzidzwa nekuda kwekugona kwazvo mukushandiswa kwakasiyana-siyana kwe nanotechnology, senge nanoelectronics, nanophotonics, uye nanomedicine. Kugona kushandisa nekudzora hunhu hweWS2 pa nanoscale kunovhura mikana mitsva yekuvandudza nanomaterials dzepamusoro uye nanodevices.

Muchidimbu,WS2 (tungsten sulfides)ine mashandisirwo anotevera:

1. WS2 inonyanya kushandiswa pakugadzira mafuta;

2. WS2 chinhu chitsva chinoshanda zvakanyanya;

3. WS2 inogona kushandiswa semafuta anozora akaoma, mafuta anozora akaoma, zvinhu zvinosanganisa mafuta zvinozvizora zvega;

4. WS2 inogadzira mafuta ekuwedzera anoshanda zvakanyanya;

5. WS2 inogona kushandiswa semafuel cells e anode, organic electrolyte battery anode, oxidation ye sulfur dioxide mu strong acid mu anode uye anode sensor;

6. WS2 inoshandiswa kugadzira zvinhu zvakagadzirwa ne nano-ceramic;

7. WS2 chinhu chakanaka che semiconductor.

Mukupedzisa,WS2, kana kuti tungsten sulfide, imusanganiswa une hunhu hwakasiyana-siyana uye mashandisirwo aunogona kuita. Hunhu hwayo hwekuzora mafuta, maitiro ayo e semiconducting, basa rayo re catalytic, uye kugona kwayo mu nanotechnology zvinoita kuti ive chinhu chinoshanduka-shanduka chine mikana yakawanda muminda yakasiyana-siyana. Sezvo tsvakiridzo muWS2 ichiramba ichienderera mberi, zvingangoita kuti tichaona zvimwe zviri kuitika uye mashandisirwo emusanganiswa uyu unonakidza mune ramangwana.
