Tuam Tshoj tus neeg muag khoom lag luam wholesale nqe CAS 12138-09-9 Tungsten Disulfide Nqe WS2 Hmoov High-Entropy Alloys

Tungsten disulfide (WS2) nyob rau hauv ntau tau siv tau ntau xyoo los ua cov roj nplua nyeem qhuav vim nws nthuav tawm cov khoom ntawm kev sib txhuam qis, tshuaj lom neeg ruaj khov, thiab thermal stability. Xyoo 1992, nws tau pom tias cov qauv ntawm WS2 ua rau nws muaj peev xwm tsim cov qauv nanotube. Cov nanotubes no yog thawj piv txwv ntawm WS2 siv los ua cov khoom siv qis. Tom qab kev tshawb pom ntawm cov txheej txheem yooj yim ntawm cov txheej txheem exfoliation los cais ib txheej ntawm 2-D cov ntaub ntawv, nws muaj peev xwm kawm txog cov khoom ntawm WS2 flakes. Nws tau pom tias, ib yam li MoS2, qhov sib txawv ntawm WS2 hloov pauv los ntawm qhov sib txawv ntawm qhov sib txawv ntawm 1.4eV mus rau qhov sib txawv ncaj qha ntawm 2eV thaum hloov los ntawm cov khoom siv ntau rau 2-D cov khoom. Vim nws qhov sib txawv ntawm qhov sib txawv, WS2 tau pom tias yog cov khoom siv nthuav dav rau ntau qhov chaw ntawm daim ntawv thov. WS2 muaj qhov sib piv siab rau / tawm hauv qhov cuam tshuam ntawm thaj chaw transistors, tswj tau spin thiab hav polarisation, muaj zog geometrical confinement ntawm excitons, thiab tunable photoluminescence. Tsis tas li ntawd, WS2 tuaj yeem ua rau muaj kev txaus siab rau thaj chaw xws li photodetectors thiab multi-junction photovoltaics. Dhau li ntawd, WS2 yog siv, nrog rau lwm yam ntaub ntawv, raws li catalyst rau hydrotreating roj crude. Lamellar tungsten disulfide yog siv los ua cov roj nplua nyeem qhuav rau fasteners, bearings, thiab pwm raws li lub npe Dicronite. Tungsten disulfide (WS2) yog siv los ua cov roj nplua nyeem uas tuaj yeem tiv taus qhov kub thiab txias. Nws kuj tseem siv tau los ua cov tshuaj tsuag roj. Tungsten sulfide yog siv los ua ib feem ntawm catalysts rau hydrotreating roj crude, hydrodesulfurization thiab hydrodenitrification cov tshuaj tiv thaiv. Nws pom daim ntawv thov raws li cov khoom siv hauv xeev theem nrab lithium roj teeb cathodes thiab lwm yam khoom siv hluav taws xob. Nws tau pom tias nws tsim inorganic nanotubes, uas yog qhov zoo dua cov tshuaj tiv thaiv zoo dua li carbon nanotubes. Tungsten sulfide ntxiv rau epoxy resin txhim kho adhesion, tawg toughness thiab strain zog tso tawm tus nqi. Tungsten sulfide muaj pseudo 2 seem qauv nrog kev siv hauv kev lag luam Petrochemical ua desulfurization catalyst. Tungsten Sulfide nanoparticles tau kos cov kev tshawb fawb txaus siab vim lawv lub peev xwm hauv cov roj ntsha hauv lub xeev; coatings thiab photocatalysts.
