Elecancytic Flakes (elecolytic manganese hlau, EMM) muaj cov ntawv thov tseem ceeb hauv kev tshuaj catalalysts. Lawv lub siab purity (ntau dua los yog sib npaug ntawm 99.7%) thiab tshuaj lom neeg ua rau lawv muaj cov khoom siv raw rau kev sib txuas ntawm ntau yam ntawm catalysts. Cov hauv qab no yog lawv lub ntsiab kev thov cov xwm txheej thiab cov kev ua haujlwm zoo hauv cov tshuaj catalysts:
I. Cov chaw thov cov chaw thov
Manganese dioxide (mnoos) catalyst prefursor
Kev siv: Elecanytic flakes tuaj yeem yog oxidised lossis yaj thiab hloov dua siab tshiab manganese dioxese, uas tau siv dav hauv:
Cov Khoom Siv Hluav Taws Xob: synthesis ntawm cathode cov ntaub ntawv rau lithium-ion roj teeb (piv txwv litium manganese oxide limyn₂o₄).
Oxidation tshuaj catalysts: piv txwv li oxidation ntawm phenol rau adipic acid, decomposition ntawm formaldehyde, thiab lwm yam.
Qhov Zoo: EMM yog tsis tshua muaj neeg ntshiab, uas txo qhov cuam tshuam ntawm impurities ntawm catalytic kev ua ub no.
Manganese sulphate (mnso₄) thiab lwm tus manganese ntsev txua synthesis
Kev siv: Desolvolving elecolytic manganese flakes los npaj manganese sulphate tov, raws li:
Chiv Chivt: LWE theem additive uas txhawb nqa photynthesis hauv cov nroj tsuag.
Tshuaj Lom Tshuaj Synthesis Catalalists: Piv txwv li ib co-catalyst nyob rau hauv Olemas Polymerisation thiab Esterification.
Organic synthesis catalyst
kev koom tes ncaj qha hauv cov tshuaj tiv thaiv:
Oxidation cov tshuaj: Manganese-Raws li catalysts yog siv rau kev xaiv oxidation ntawm cov cawv rau cov dej cawv lossis kua qaub (piv txwv li oxidation ntawm Phenol).
Hydrogenation cov tshuaj tiv thaiv: manganese-txhawb kev catalysts (piv txwv MN / C) tau siv rau kev siv hydrogenation ntawm unsaturated tebchaw.
Qhov Zoo: Ntau ntau oxidation xeev ntawm manganese (mn²⁺, mnÃ, mn⁴⁺) muab nws yoog cov kev ua kom haum.
Kev tiv thaiv ib puag ncig catalyststs
Denitrication (SC) catalysts: Siv ua ke nrog Vanadium thiab Tungsten kom tsis lees txais cov pa roj (txo cov pa tawm).
Vocs Kho: Manganese-based catalysts (piv txwv li mno₂ / tio₂) degrade volatile volatile cov organic sib xyaw.
Kev Kho Mob Dej: catalytic ozation rau qhov kev tshwm sim ntawm cov pa phem ntawm cov orgeicants (EG DES ZOOV LOJ).
2. Kev ua haujlwm zoo thiab cov yam ntxwv khoom
Siab Purity Qhov Zoo
Purity ntau dua los yog sib npaug ntawm 99.7%, kom nquag plias qhov chaw ntawm cov catalalyst tsis muaj kev cuam tshuam los ntawm impurities (piv txwv li cov khoom siv tawm (EG FE).
Dhau ICP-MS thiab lwm yam kev sim thiab ntawv pov thawj, muab cov ntaub ntawv qhia kom zoo.
Daim ntawv thiab particle loj customization
Flaky: Ib qho yooj yim khaws thiab thauj, thiab siv ua kua theem catalytic tshuab tom qab kev xaus.
HMOOV ({{0 {0}} mesh): siv ncaj qha hauv cov khoom-theem catalysis lossis rau kev npaj ntawm kev txhawb nqa catalysts.
Nqi-Zoo
Piv rau lwm cov khoom siv hlau nplaum uas muaj txiaj ntsig thiab palladium), manganese-based catalysts tsis tshua muaj nqi thiab haum rau cov ntawv thov loj.
3. Cov txheej txheem raug thiab rooj plaub
Manganese dioxide catalyst npaj cov txheej txheem
Luam mus luam
Elec graphetic flake → acid dissolution (hso₄) → oxideidation (h₂o₂ / ₃) → precipination → mnoous catalyst
Daim Ntawv Thov Piv Txwv: Lub chaw tsim hluav taws xob Lithium roj teeb siv tau emm-synthesized lithium manganese oxide, uas txhim kho lub roj teeb lub neej ntawm 15%.
Manganese-based screnitrification catalyst
cov lus ntawm ib txoj kab ke: V₂o₅-wo₃ / ti₂ nrog ntxiv mno₂ los txhim kho kev ua haujlwm tsawg (150-300 degree).
Ua rau: Cov nroj tsuag denitricalic ntawm lub zog cog qoob loo nce los ntawm 85% mus rau 92%, thiab nws txoj kev tawm tsam rau cov txhaurfur lom tau txhim kho.
