Mixed Metal Oxide (MMO) electrodes, tseem hu ua Dimensionally Stable Anodes (DSA), yog cov khoom siv hluav taws xob tsim los ntawm kev siv cov txheej txheem thermally decomposed ntawm electrocatalytically nquag sib xyaw hlau oxides rau hauv lub valve hlau substrate (feem ntau titanium).
Core Structure
Substrate: Feem ntau titanium (Ti), xaiv rau nws lub peev xwm los tsim ib txheej tuab passivation (TiO₂) uas muab tshwj xeeb corrosion kuj nyob rau hauv anodic polarization.
Catalytic Txheej: Ib txheej nyias (feem ntau ntau micrometers mus rau kaum micrometers tuab) muaj li ntawm ob lossis ntau dua hlau oxides. Cov txheej no ua haujlwm raws li "tus ntsuj plig" ntawm cov electrode, ua kom muaj hluav taws xob conductivity thiab cov tshuaj tiv thaiv catalytic.
Txoj Cai Ua Haujlwm: Thaum lub titanium substrate nws tus kheej tsis yog -conductive, MMO txheej ua ob qho tib si hluav taws xob zoo tshaj plaws thiab cov khoom siv hluav taws xob zoo heev. Nws txo qis qhov muaj peev xwm dhau ntawm lub hom phiaj cov tshuaj tiv thaiv, ua kom muaj txiaj ntsig zoo ntawm cov hluav taws xob hloov mus rau hauv tshuaj lom neeg lub zog thaum tiv thaiv lub hauv paus titanium substrate los ntawm corrosion.
Cov yam ntxwv tseem ceeb ntawm MMO Electrodes
►Exceptional Electrocatalytic Activity
MMO txheej yog tsim los ua kom pom kev ua haujlwm siab rau cov tshuaj tiv thaiv tshwj xeeb (piv txwv li, Chlorine Evolution Reaction, CER), txo qis qhov xav tau ntau dhau. Qhov no ua rau txo qis ntawm tes hluav taws xob thiab kev siv hluav taws xob (ua tiav 15% -30% kev txuag hluav taws xob piv rau cov khoom siv hluav taws xob graphite).
► Zoo Dimensional Stability
Cov txheej txheej ruaj khov ua raws li titanium substrate, tiv thaiv kev noj thiab deformation thaum electrolysis-tsis zoo li graphite electrodes. Lub geometric qhov ntev ntawm cov electrode tseem zoo li tsis hloov pauv thoob plaws hauv nws lub neej, yog li lub npe "Dimensionally Stable Anode." Qhov no ua kom muaj kev ruaj ntseg ua haujlwm thiab kev faib tawm tam sim no hauv cov hlwb electrolytic.
►Exceptionally Long Service Life
Ua tsaug rau qhov kev tiv thaiv zoo tshaj plaws ntawm ob txheej txheej thiab titanium substrate, MMO electrodes tuaj yeem siv tau rau xyoo lossis ntau tshaj kaum xyoo, deb tshaj lub neej ntawm cov graphite electrodes (hli) lossis txhuas-raws li anodes (1-2 xyoos). Qhov no ua rau txo cov nqi tu thiab kev poob qis uas cuam tshuam nrog kev hloov electrode.
►Excellent Environmental Compatibility thiab khoom Purity
Cov electrode nws tus kheej tsis koom nrog cov tshuaj tiv thaiv, tsis txhob muaj kev sib kis ntawm cov khoom siv hluav taws xob thiab cov electrolytes los ntawm corrosion (ib qho teeb meem nrog graphite anodes). Nws kuj tseem tshem tawm txoj kev pheej hmoo ntawm cov hlau hnyav uas cuam tshuam nrog cov hlau lead-raws li anodes.
►Customizable Catalytic Selectivity
Los ntawm kev sib txawv ntawm hom thiab qhov sib piv ntawm cov hlau oxides hauv txheej, cov electrode qhov kev ua tau zoo tuaj yeem "tsim" kom pom cov kev xaiv siab rau cov kev xav tshwj xeeb. Piv txwv li, ruthenium-raws li cov txheej txheem tseem ceeb rau Chlorine Evolution Reaction (CER), thaum iridium-raws li cov coatings nyiam Oxygen Evolution Reaction (OER).
Thawj daim ntawv thov teb
Chlor{0}}Alkali Kev Lag Luam
Daim ntawv thov: Electrolysis ntawm brine los tsim cov tshuaj chlorine (Cl₂), sodium hydroxide (NaOH), thiab hydrogen (H₂). Qhov no yog qhov ntxov tshaj plaws thiab tseem ceeb tshaj plaws ntawm MMO electrodes, ua lub hauv paus ntawm lawv txoj kev loj hlob.
Antifouling ntawm Seawater Electrolysis
Daim ntawv thov: Onboard lossis cov chaw ntug dej hiav txwv electrolyze dej hiav txwv los tsim sodium hypochlorite (NaClO), siv los tshem tawm cov kab mob thiab tiv thaiv biofouling hauv cov kav dej thiab cov condensers.
Industrial Wastewater Treatment
Daim ntawv thov: Direct electrochemical oxidation ntawm cov tshuaj lom organic tebchaw (piv txwv li, phenols, cyanides) nyob rau hauv cov dej khib nyiab, los yog indirect tiam ntawm muaj zog oxidants (xws li, hypochlorite, ozone) rau tshuaj tua kab mob thiab decolorization.
Kev tiv thaiv Cathodic
Daim ntawv thov: Siv raws li kev txaus siab tam sim no anodes los tiv thaiv cov qauv hlau xws li chaw nres nkoj, nkoj, thiab cov kav dej faus los ntawm electrochemical corrosion. MMO anodes yog qhov kev xaiv zoo tshaj vim lawv lub neej ntev thiab kev ua haujlwm siab.
