    Isicelo

    1. I-Nano WS2 isetyenziswa kakhulu njenge-petroleum catalyst: ingasetyenziselwa njenge-hydrodesulfurization catalyst, kwaye ingasetyenziselwa njenge-catalyst ye-polymerization, i-reforming, i-hydration, i-dehydration kunye ne-hydroxylation. Inokusebenza kakuhle kokuqhekeka kunye nomsebenzi ozinzile kunye nothembekileyo we-catalytic. Ubomi benkonzo ende kunye nezinye iimpawu zithandwa kakhulu phakathi kwe-petroleum refineries;

    2. Kwitheknoloji yokulungiselela i-inorganic functional materials, i-nano WS2 luhlobo olutsha lwe-catalyst ephezulu. Ngenxa yekhompawundi entsha enokwenza isakhiwo sesandwich, i-nano i-WS2 ingenziwa ibe yi-monolayer ye-dimensional material, kwaye inokubuyiselwa kwakhona njengoko kufuneka ibe nenkulu kakhulu Isixhobo esitsha se-granular "sesakhiwo segumbi lomgangatho" sangaphakathi. indawo, kunye nezixhobo zokudibanisa zingadityaniswa ngexesha lenkqubo yokupakisha kwakhona ukwenza i-catalyst okanye umboniso obuthathaka kunye ne-superconducting material. Indawo yayo enkulu yangaphakathi kulula ukuxutywa kunye ne-accelerators. Yiba luhlobo olutsha lwe-catalyst esebenzayo. I-Nagoya Industrial Research Institute yaseJapan yafumanisa ukuba i-nano-WS2 inempembelelo enkulu ekuguqulweni kwe-CO2 kwi-CO, eya kukhuthaza ukuphuhliswa kobugcisa bomjikelezo wekhabhoni kwaye ivule indlela yokuphucula ukufudumala kwehlabathi;

    3. I-WS2 ingasetyenziswa njengezithambisi eziqinileyo, izithambisi zefilimu ezomileyo, imathiriyeli ehlanganisiweyo yokuzithambisa: INano WS2 yeyona nto ilubricant eqinileyo, ene-friction coefficient ye-0.01~0.03, amandla acinezelayo ukuya kuthi ga kwi-2100 MPa, kunye neasidi nealkali ukumelana nomhlwa. Ukumelana nomthwalo olungileyo, okungeyotyhefu kwaye akukho bungozi, ubushushu bokusetyenziswa ngokubanzi, ubomi obude bokuthambisa, ulwelo oluphantsi kunye nezinye izibonelelo. Kwiminyaka yakutshanje, ukukhuhlana okuphantsi kakhulu kunye nokunxiba okuboniswe sisithambiso esiqinileyo se-fulerene nano WS2 sitsale umdla wabantu. Ukunciphisa ngokuphawulekayo i-friction factor kunye nokwandisa ubomi besikhunta;

    4. INano WS2 sisongezo esibaluleke kakhulu sokwenza izithambisi ezisebenza kakhulu. Uphononongo lufumene ukuba ukongeza inani elifanelekileyo le-WS2 nanoparticles kwi-oyile yokuthambisa kunokuphucula kakhulu ukusebenza kwe-oyile yokuthambisa, ukunciphisa i-friction factor nge-20% -50%, kunye nokwandisa amandla efilimu yeoli nge-30% -40%. Ukusebenza kwayo kokuthambisa kungcono kakhulu kune-nano-MoS2. Ngaphantsi kweemeko ezifanayo, ukusebenza kwe-lubricating ye-oyile yesiseko eyongeziweyo kunye ne-nano WS2 ingcono kakhulu kunokuba i-oyile yesiseko eyongezwe ngamasuntswana aqhelekileyo, kwaye inozinzo oluhle lwe-dispersion. Iziphumo zophononongo zibonisa ukuba izithambiso ezongeziweyo nge-nano-particles zidibanisa iingenelo zokuthambisa ulwelo kunye nokuthambisa okuqinileyo, okulindeleke ukuba kufezekiswe ukuthambisa ukusuka kwigumbi lobushushu ukuya kumaqondo obushushu aphezulu (ngaphezu kwama-800 ℃). Ke ngoko, i-nano WS2 ingasetyenziswa njengesongezo sokudibanisa inkqubo entsha yokuthambisa, enethuba elibanzi lokusetyenziswa;

    5. Inokusetyenziswa kwakhona njenge-anode ye-fuel cell, i-anode ye-organic electrolyte ibhetri ehlaziywayo, i-anode ye-sulphur dioxide oxidized kwi-asidi eqinile kunye ne-anode yenzwa, njl.;

    6. Isetyenziselwa ukwenza izinto ezidibeneyo ze-nano-ceramic;

    7. Yimpahla efanelekileyo ye-semiconductor.

    Ugcino

    Le mveliso kufuneka ivalwe kwaye igcinwe kwindawo eyomileyo nepholileyo. Akufanele kuvezwe emoyeni ixesha elide ukuthintela i-agglomeration ngenxa yokufuma, okuya kuchaphazela ukusebenza kokusasazwa kunye nokusetyenziswa kwesiphumo. Ukongeza, thintela uxinzelelo olunzima kwaye ungaqhagamshelani nee-oxidants. Ezothutho njengempahla eqhelekileyo.
