1. Cheeb tsam catalytic
(1) sulfuric acid kev lag luam (daim ntawv thov tseem ceeb)
Lub Luag Hauj Lwm: Ua HaujlwmRaws li ib tug catalyst rau luboxidation ntawm so₂ rau so₃(Hu rau cov txheej txheem rau kev tsim cov sulfuric acid).
Mechanism:V₂o₅ thiab k₂o / sio₂ ua catalyst, oxygen atoms pauv raws lub voj voog v⁵⁺↔v⁴⁺:
Yog li 2+ v2o5 → yog {{v2o4v2o {} o2} → v2o5
Qhov Zoo: Kev ua haujlwm siab, tus nqi qis, tuaj yeem hloov platinum cov platinum catalysts.
(2) catalysis ntawm cov organic synthesis
Xaiv Oxidation:
Benzene → Mamic anhydride (siv hauv cov yas).
Propane / propylene → acrylic acid (hluavtaws acrylic cob).
Dehydrogenation cov tshuaj tiv thaiv: Ethylbenzene → styrene (cov khoom siv raw rau polystyrene).
Ib puag ncig canalysis: catalytic decomposition of nitrogen oxides (tsis muaj) thiab organic paug nyob rau hauv cov pa roj cua.
2. Lub zog cia thiab cov khoom siv roj teeb
(1) Vanadium redox rechargeable roj teeb (vrfb)
Ua Haujlwm:Raws li ib qho khoom siv nquag ntawm cov electrolyte, nws khaws lub zog los ntawm redox cov tshuaj tiv thaiv v⁵⁺ / v⁴⁺ (anode) thiab v³ / v²⁺ (Cathode).
Qhov Zoo:
Long service life (>20, 000 cmles).
Haum rau loj-teev lub zog cia (piv txwv li cua thiab lub hnub ci fais fab ntoo).
(2) Lithium-ion / Sodium-ion roj teeb
Cov Khoom Siv Hauv Qhov Chaw Zoo:
Lub fawm kib tuaj yeem embed li⁺ lossis na⁺, nrog lub siab zoo capacitance capacitance (~ 294 mAh / g).
Kev hloov kho cov tswv yim (xws li nanization thiab carbon quav paug) txhim kho kev coj ua thiab kev ruaj khov ntawm lub voj voog.
Daim Ntawv Thov Kev Pab Cuam: Muaj Zog Zog Hluav Taws Xob Roj Roj Teeb, Cov Khoom Hluav Taws Xob Uas Yooj Yim.
3. Tshuaj Kev Lag Luam thiab Khoom Ntau Lawm
(1) ceramics thiab iav
Xim: Qhov sib ntxiv ntawm v₂o₅ ua cov daj lossis ntsuab ceramic ci.
UV Kev Nyuaj Siab: Siv nyob rau hauv tsom iav tshwj xeeb (piv txwv li rau thermal rwb thaiv tsev ntawm cov tuam tsev).
(2)Cov ntaub ntawv nyoos rauZus Tau Tej Cov Voj Hlau Hlau Thiab Alloys: Vanadium Hlau yog tsim los ntawm Aluminoticmic lossis Calcium Txo:
V2o {{5+5 ca → 2 {+5 Cao
Daim ntawv thov ntawm alloys:
Vanadium Steel(Fe-v): Siv zog ntxiv thiab corrosion tsis kam (siv hauv Tool Steel thiab chaw tsheb).
Titanium Alloy(Ti {-6 al -4 v): cov khoom siv rau kev lag luam aerospace.
(3) synthesis ntawm lwm cov tebchaw
Vanadium nitride (vn):ib tug hnav-resistant txheej txheej txheej.
Tsev vanadates(piv txwv li, ago₃): cov tshuaj tiv thaiv thiab kev xeb txwv tsis pub muaj.
