I-Tungsten Sulfide(WS2): Ukusebenza kanye Nokusetshenziswa

I-WS2, eyaziwa nangokuthi i-tungsten sulfide igrey, uhlelo olunezinhlangothi eziyisithupha, i-semiconductor kanye ne-diamagnetic. Ine-coefficient ephansi kakhulu yokungqubuzana (0.03), ukumelana okuphezulu kakhulu kwengcindezi kanye nokumelana ne-oxidation (ukubola kuqala ku-450 ℃ emoyeni, Ifanele ukushisa okuphezulu, ukucindezela okuphezulu, i-vacuum ephezulu, umthwalo ophezulu, isivinini esikhulu, imisebe ephezulu, ukugqwala okunamandla, izinga lokushisa eliphansi kakhulu kanye nezinye izimo ezinzima.

I-WS2 / tungsten sulfides / tungsten disulfides / tungsten (IV)I-sulfide iyinhlanganisela ebilokhu ithola ukunakwa emphakathini wesayensi ngenxa yezakhiwo zayo ezihlukile kanye nezinhlelo zokusebenza ezingaba khona. Kulesi sihloko, sizohlola ukuthi iyini i-WS2, izakhiwo zayo, kanye nokusetshenziswa kwayo okungaba khona emikhakheni eyahlukahlukene.

I-WS2iyinhlanganisela eyenziwe ngama-athomu e-tungsten ne-sulfur, enefomula yamakhemikhali engu-W(S2). Ingowomndeni wama-dichalcogenides ensimbi eguqukayo (ama-TMD), okuyizinto ezihlanganisiwe ezinesakhiwo esifana ne-graphene. I-WS2 inesakhiwo esinezingqimba esakhiwe ngama-athomu e-tungsten ahlanganiswe phakathi kwezingqimba zama-athomu e-sulfur. I-WS2 isebenzisa isakhiwo esinezingqimba esihlobeneI-MoS2(i-Molybdenum Disulfide), enama-athomu e-W akhiwe endaweni yokuxhumanisa i-trigonal prismatic, Lesi sakhiwo esinezingqimba sinikeza i-WS2 izakhiwo zayo eziyingqayizivele futhi siyenza ibe yinto ethokozisayo yocwaningo lwesayensi kanye nezinhlelo zokusebenza zobuchwepheshe.

Enye yezimpawu eziphawuleka kakhulu zeI-WS2yizici zayo zokugcoba. I-WS2 ine-coefficient ephansi yokungqubuzana, okwenza ibe yi-lubricant enhle kakhulu yezinhlelo zokusebenza ezahlukahlukene. Isetshenziswe njenge-lubricant eqinile ezindaweni ezinokushisa okuphezulu kanye nokucindezela okuphezulu, njengasezimbonini zezindiza kanye nezimoto. Isakhiwo esinezingqimba se-WS2 sivumela ukuthi isheleleke kalula phezu komunye nomunye, kunciphisa ukungqubuzana kanye nokuguguleka phakathi kwezindawo.

Ngaphezu kwezakhiwo zayo zokugcoba,I-WS2futhi ikhombisa ukuziphatha kwe-semiconducting. Lokhu kusho ukuthi ingasetshenziswa kumadivayisi kagesi kanye nezinhlelo zokusebenza ze-optoelectronic. I-WS2 ibonise amandla okusetshenziswa kuma-transistors, ama-photodetector, kanye namaseli elanga ngenxa yezakhiwo zayo ezihlukile ze-elekthronikhi. Amandla ayo okumunca nokukhipha ukukhanya ngempumelelo ayenza ibe yinto ethembisayo kumadivayisi e-optoelectronic esizukulwane esilandelayo.

Ngaphezu kwalokho,I-WS2kuye kwacwaningwa amandla ayo ekusetshenzisweni kwe-catalysis kanye nokugcinwa kwamandla. Indawo yayo ephezulu kanye nomsebenzi wayo we-catalytic kwenza kube yinto ethembisayo yokusetshenziswa kumaseli kaphethiloli, ukusabela kokuvela kwe-hydrogen, kanye nezinye izinqubo ze-catalytic. Izinto ezisekelwe ku-WS2 nazo zihlolisisiwe amandla azo kumadivayisi okugcina amandla, njengamabhethri nama-supercapacitor, ngenxa yokuqhuba kwawo okuphezulu kanye nezakhiwo ze-electrochemical.

Izakhiwo eziyingqayizivele zeI-WS2futhi kudonsele isithakazelo emkhakheni we-nanotechnology. Ama-nanoparticles e-WS2 nama-nanosheet ahlanganiswe futhi afundwa ngenxa yamandla awo ezinhlelweni ezahlukene ze-nanotechnology, njenge-nanoelectronics, i-nanophotonics, kanye ne-nanomedicine. Amandla okulawula nokulawula izakhiwo ze-WS2 ku-nanoscale avula amathuba amasha okuthuthukiswa kwama-nanomaterials athuthukile kanye nama-nanodevices.

Ngokufigqiwe,I-WS2 (ama-sulfide e-tungsten)inezindlela ezilandelayo zokusebenzisa:

1. I-WS2 isetshenziswa kakhulu kuma-catalyst kawoyela;

2. I-WS2 iyisikhuthazi esisha esisebenza kahle kakhulu;

3. I-WS2 ingasetshenziswa njengezithambisi eziqinile, izithambisi zefilimu eyomile, izinto ezihlanganisiwe ezizigcobayo;

4. I-WS2 iwukudala izithasiselo zokuthambisa ezisebenza kahle kakhulu;

5. I-WS2 ingasetshenziswa njengamaseli kaphethiloli e-anode, i-anode yebhethri ye-electrolyte ephilayo, i-oxidation ye-sulfur dioxide ku-asidi enamandla ku-anode kanye ne-sensor ye-anode;

6. I-WS2 isetshenziselwa ukwenza izinhlanganisela ze-nano-ceramic;

7. I-WS2 iyinto enhle ye-semiconductor.

Ekuphetheni,I-WS2, noma i-tungsten sulfide, iyinhlanganisela enezakhiwo eziningi ezihlukile kanye nezicelo ezingaba khona. Izakhiwo zayo zokugcoba, ukuziphatha kwe-semiconducting, umsebenzi we-catalytic, kanye nekhono ku-nanotechnology kuyenza ibe yinto eguquguqukayo enamathemba athembisayo emikhakheni eyahlukahlukene. Njengoba ucwaningo lwe-WS2 luqhubeka luthuthuka, kungenzeka ukuthi sizobona intuthuko eyengeziwe kanye nokusetshenziswa kwale nhlanganisela ethakazelisayo esikhathini esizayo.
