    Daim ntawv thov

    1. Nano WS2 feem ntau yog siv los ua cov roj av catalyst: nws tuaj yeem siv los ua hydrodesulfurization catalyst, thiab nws tseem tuaj yeem siv los ua cov catalyst rau polymerization, hloov pauv, dej, lub cev qhuav dej thiab hydroxylation. Nws muaj kev ua haujlwm zoo tawg thiab ruaj khov thiab txhim khu kev qha catalytic. Lub neej ua haujlwm ntev thiab lwm yam ntxwv yog nrov heev ntawm cov roj av refineries;

    2. Nyob rau hauv kev npaj technology ntawm inorganic functional cov ntaub ntawv, nano WS2 yog ib yam tshiab ntawm high-efficiency catalyst. Vim yog cov khoom sib xyaw tshiab uas tuaj yeem tsim cov qauv sandwich, nano WS2 tuaj yeem ua rau hauv cov khoom siv monolayer ob sab, thiab tuaj yeem rov qab tau raws li qhov xav tau kom muaj cov khoom loj heev Cov khoom siv tshiab ntawm "cov qauv hauv pem teb" ntawm sab hauv. qhov chaw, thiab cov ntaub ntawv intercalation tuaj yeem muab ntxiv thaum lub sijhawm rov ua cov txheej txheem kom nws ua cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob thiab cov khoom siv superconducting. Nws qhov loj hauv cheeb tsam sab hauv yog yooj yim los sib xyaw nrog cov accelerators. Ua ib yam tshiab ntawm high-efficiency catalyst. Lub koom haum Nagoya Industrial Research Institute ntawm Nyij Pooj tau tshawb pom tias nano-WS2 muaj cov txiaj ntsig zoo hauv kev hloov pauv ntawm CO2 rau CO, uas yuav txhawb nqa kev txhim kho ntawm cov pa roj carbon monoxide thev naus laus zis thiab ua txoj hauv kev los txhim kho cov qauv ntawm lub ntiaj teb sov sov;

    3. WS2 tuaj yeem siv los ua cov khoom siv roj nplua nyeem, cov khoom siv roj hmab qhuav, cov khoom siv lubricating tus kheej: Nano WS2 yog cov roj nplua nyeem zoo tshaj plaws, nrog kev sib txhuam coefficient ntawm 0.01 ~ 0.03, compressive zog txog li 2100 MPa, thiab acid thiab alkali. corrosion kuj. Kev ua haujlwm zoo, tsis muaj tshuaj lom thiab tsis muaj mob, siv dav dav, lub neej ntev lubrication, tsis tshua muaj kev sib txhuam thiab lwm yam zoo. Nyob rau hauv xyoo tas los no, kev sib txhuam ultra-tsawg thiab hnav pom los ntawm cov khoom siv roj nplua nyeem hollow fullerene nano WS2 tau nyiam cov neeg nyiam. Qhov tseem ceeb txo qhov kev sib txhuam thiab ua kom lub neej ntawm pwm;

    4. Nano WS2 yog ib qho tseem ceeb ntxiv rau kev tsim cov roj nplua nyeem ua haujlwm siab. Cov kev tshawb fawb pom tau hais tias ntxiv qhov tsim nyog ntawm WS2 nanoparticles rau cov roj lubricating tuaj yeem txhim kho cov kev ua tau zoo ntawm cov roj lubricating, txo cov kev sib txhuam ntawm 20% -50%, thiab nce cov roj zaj duab xis zog los ntawm 30% -40%. Nws cov lubricating kev ua tau zoo tshaj li nano-MoS2. Nyob rau hauv tib lub sijhawm, lub lubricating kev ua tau zoo ntawm cov roj hauv paus ntxiv nrog nano WS2 yog qhov zoo dua li cov roj hauv paus ntxiv nrog cov khoom sib xyaw ua ke, thiab nws muaj kev ruaj ntseg zoo. Cov txiaj ntsig ntawm txoj kev tshawb fawb qhia tau hais tias cov roj nplua nyeem ntxiv nrog nano-particles ua ke cov txiaj ntsig zoo ntawm cov kua roj lubrication thiab cov roj lubrication, uas yuav tsum ua kom tiav lubrication ntawm chav tsev kub mus rau qhov kub siab (dhau 800 ℃). Yog li ntawd, nano WS2 tuaj yeem siv los ua cov khoom siv ntxiv rau kev sib txuas cov txheej txheem lubricating tshiab, uas muaj cov ntawv thov dav dav;

    5. Nws kuj tseem siv tau los ua anode ntawm roj cell, anode ntawm cov organic electrolyte rechargeable roj teeb, anode ntawm sulfur dioxide oxidized nyob rau hauv muaj zog acid thiab anode ntawm sensor, thiab lwm yam .;

    6. Siv los ua cov khoom siv nano-ceramic;

    7. Nws yog cov khoom siv semiconductor zoo.

    Cov khoom no yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw qhuav thiab txias. Nws yuav tsum tsis txhob raug huab cua ntev ntev los tiv thaiv agglomeration vim noo noo, uas yuav cuam tshuam rau kev ua haujlwm dispersion thiab siv cov nyhuv. Tsis tas li ntawd, tsis txhob hnyav hnyav thiab tsis txhob sib cuag nrog oxidants. Thauj raws li cov khoom lag luam.
