    Isicelo

    1. I-Nano WS2 isetshenziswa kakhulu njenge-catalyst ye-petroleum: ingasetshenziswa njenge-catalyst ye-hydrodesulfurization, futhi ingasetshenziswa njenge-catalyst ye-polymerization, ukuguqulwa, i-hydration, ukuphelelwa amandla kwamanzi kanye ne-hydroxylation. Inokusebenza okuhle kokuqhekeka nomsebenzi ozinzile nothembekile we-catalytic. Impilo ende yesevisi nezinye izici zithandwa kakhulu phakathi kwezindawo zokuhluza i-petroleum;

    2. Kubuchwepheshe bokulungiselela bezinto ezisebenzayo ezingaphili, i-nano WS2 iwuhlobo olusha lwe-catalyst esebenza kahle kakhulu. Ngenxa yenhlanganisela entsha engakha isakhiwo sesemishi, i-nano WS2 ingenziwa ibe yi-monolayer enezinhlangothi ezimbili, futhi ingafakwa kabusha njengoba kudingeka ukuze ibe nenkulu kakhulu Impahla entsha eyimbudumbudu "yesakhiwo segumbi lesitezi" sangaphakathi. isikhala, nezinto zokuhlanganisa zingangezwa phakathi nenqubo yokupakisha kabusha ukuze kuyenze ibe yi-catalyst noma isibonisi esibucayi kanye nezinto ezithinta i-superconducting. Indawo yayo enkulu yangaphakathi kulula ukuyixuba nama-accelerator. Iba uhlobo olusha lwe-catalyst esebenza kahle kakhulu. I-Nagoya Industrial Research Institute yase-Japan ithole ukuthi i-nano-WS2 inomphumela omuhle kakhulu ekuguqulweni kwe-CO2 ibe yi-CO, okuzogqugquzela ukuthuthukiswa kobuchwepheshe bomjikelezo wekhabhoni futhi kuvule indlela yokuthuthukisa ukuthambekela kokufudumala kwembulunga yonke;

    3. I-WS2 ingasetshenziswa njengezithambisi eziqinile, okokugcoba kwefilimu eyomile, izinto eziyinhlanganisela ezizithambisayo: I-Nano WS2 iyilubricant eqinile engcono kakhulu, ene-friction coefficient engu-0.01–0.03, amandla acindezelayo afika ku-2100 MPa, kanye ne-asidi ne-alkali ukumelana nokugqwala. Ukumelana kahle nomthwalo, okungeyona ubuthi futhi akunangozi, izinga lokushisa elibanzi lokusetshenziswa, impilo ende yokugcoba, isici esiphansi sokungqubuzana nezinye izinzuzo. Eminyakeni yamuva nje, ukungqubuzana nokuguga okuphansi kakhulu okuboniswa i-lubricant eqinile engenalutho i-fulerene nano WS2 idonse ukunaka kwabantu. Ukunciphisa ngokuphawulekayo isici sokungqubuzana futhi ukwandise ukuphila kwesikhunta;

    4. I-Nano WS2 iyisengezo esibaluleke kakhulu sokukhiqiza izithambisi ezisebenza kahle kakhulu. Ucwaningo luthole ukuthi ukwengeza inani elifanele lama-nanoparticles e-WS2 kuwoyela wokugcoba kungathuthukisa kakhulu ukusebenza kokugcoba kwamafutha okugcoba, kunciphise i-friction factor ngo-20% -50%, futhi kwandise amandla efilimu kawoyela ngo-30% -40%. Ukusebenza kwayo kokugcoba kungcono kakhulu kune-nano-MoS2. Ngaphansi kwezimo ezifanayo, ukusebenza kokugcoba kwamafutha esisekelo angezwe nge-nano WS2 kungcono kakhulu kunowoyela wesisekelo ongezwe ngezinhlayiya ezivamile, futhi unokuzinza okuhle kokuhlakazeka. Imiphumela yocwaningo ikhombisa ukuthi izinto zokugcoba ezengezwe nezinhlayiya ze-nano zihlanganisa izinzuzo zokuthambisa uketshezi kanye nokugcotshwa okuqinile, okulindeleke ukuthi kuzuze ukugcotshwa kusuka kumazinga okushisa asekamelweni kuya kumazinga okushisa aphezulu (ngaphezu kuka-800 ℃). Ngakho-ke, i-nano WS2 ingasetshenziswa njengesengezo ukuze kuhlanganiswe uhlelo olusha lokuthambisa, olunamathemba abanzi okusebenza;

    5. Ingasetshenziswa futhi njenge-anode ye-fuel cell, i-anode yebhethri ye-organic electrolyte ephindwe kabusha, i-anode ye-sulphur dioxide oxidized ku-asidi eqinile kanye ne-anode yenzwa, njll.;

    6. Isetshenziselwa ukwenza izinto ezihlanganisiwe ze-nano-ceramic;

    7. Yimpahla enhle ye-semiconductor.

    Isitoreji

    Lo mkhiqizo kufanele uvalwe futhi ugcinwe endaweni eyomile nepholile. Akufanele kuvezwe emoyeni isikhathi eside ukuvimbela i-agglomeration ngenxa yomswakama, okuzothinta ukusebenza kokuhlakazeka kanye nomphumela wokusetshenziswa. Ngaphezu kwalokho, gwema ukucindezela okunzima futhi ungaxhumani nama-oxidants. Ezokuthutha njengezimpahla ezijwayelekile.
