1. Cheeb tsam catalytic
(1) sulfuric acid kev lag luam (daim ntawv thov tseem ceeb)
Lub luag haujlwm:ua yeeb yam raws li ib tug catalyst rauoxidation 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 mus los ntawm V⁵⁺↔v⁴⁺ Caunor:
So2 + V2 O5 → SO3 + V2 O4 V2 O6 {{{}} → v2 o5
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 roj teeb {{}} roj teeb (vrfb)
Ua Haujlwm:Ua ib qho khoom siv nquag ntawm cov electrolyte, nws tau ua lub zog vim yog cov tshuaj tiv thaiv redox
Qhov Zoo:
Длительный срок службы (>20 000 cmles).
Haum rau loj-teev lub zog cia (piv txwv li cua thiab lub hnub ci fais fab ntoo).
(2) lithium {{1} ion / sodium {{2} ion roj teeb
Cov Khoom Siv Hauv Qhov Chaw Zoo:
Fawm kib tuaj yeem embed li⁺ lossis na⁺, nrog lub peev xwm siab tshaj plaws (~ 294 mAh / g).
Cov txheej txheem kev hloov kho (xws li threading thiab carbon txheej) txhim kho coj zoo thiab voj voog ruaj khov.
Daim Ntawv Thov Kev Pab Cuam: Muaj Zog Zog Hluav Taws Xob Roj Roj Teeb, Cov Khoom Hluav Taws Xob Uas Yooj Yim.
3. Kev Siv Tshuaj thiab Khoom Raug
(1) ceramics thiab iav
Dyes: Ntxiv v₂o₅ ua lub daj lossis ntsuab ceramic ci.
Ultraviolet nqus tau: 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 rauKev tsim cov hlau vanadium thiab alloys: hlau vanadium yog tsim los ntawm aluminoticmic lossis calcium txo txoj kev:
V2o {{5+5 ca → 2 {+5 Cao
Daim ntawv thov ntawm alloys:
Vanadium Steel(Fe - v): nce lub zog thiab corrosion tsis kam (siv hauv Tool Steel thiab chaw tsheb).
Titanium Alloy(Ti-6al-4V): cov khoom siv rau kev lag luam hauv aerospace.
(3) synthesis ntawm lwm cov tebchaw
Vanadium nitride (vn): Hnav-resistant txheej cov khoom siv.
Tsev vanadates(Piv txwv): Navo₃): Cov tshuaj tiv thaiv thiab kev xeb dej tsis pub muaj.
