Hauv electrolysis ntawm brine (ib qho kev daws ntawm sodium chloride los yog cov ntsev ntau hauv dej), ntau yam khoom siv anode tuaj yeem siv tau nyob ntawm qhov tshwj xeeb ntawm cov txheej txheem electrolysis. Ntawm no yog ob peb feem ntau siv anode cov ntaub ntawv rau brine electrolysis:
Graphite Anode: Graphite anodes nquag siv hauv brine electrolysis vim lawv tus nqi qis, hluav taws xob zoo, thiab tsis kam tiv thaiv corrosion hauv ib puag ncig chloride-nplua nuj. Lawv tuaj yeem tiv taus qhov hnyav thiab muab kev ua haujlwm ruaj khov thaum lub sijhawm electrolysis.
Titanium MMO Anode: Titanium anodes coated nrog sib xyaw hlau oxide (MMO) txheej yog ib qho kev xaiv nrov rau brine electrolysis. MMO txheej, feem ntau muaj ruthenium, iridium, lossis platinum catalysts, txhim khu lub anode txoj haujlwm electrochemical, durability, thiab tsis kam mus rau chlorine evolution.
Platinum: Platinum paub txog nws cov kev ua haujlwm catalytic zoo heev thiab kev tiv thaiv corrosion, ua rau nws cov khoom siv zoo anode rau dej electrolysis. Nws pab txhawb cov pa oxygen evolution cov tshuaj tiv thaiv (OER) ntawm lub anode, ua kom muaj txiaj ntsig zoo ntawm cov pa oxygen.
IrO2 (Iridium Dioxide): Iridium dioxide yog lwm cov khoom siv anode nrov rau dej electrolysis. Nws muaj cov tshuaj lom neeg ruaj khov, zoo heev conductivity, thiab durability nyob rau hauv hnyav ua hauj lwm tej yam kev mob. IrO2-raws li anodes muaj kev ua haujlwm catalytic zoo rau OER.
RuO2 (Ruthenium Dioxide): Ruthenium dioxide feem ntau siv ua ke nrog iridium dioxide ua cov hlau oxide (MMO) txheej ntawm titanium substrates. MMO anode configuration no muab kev txhim kho catalytic kev ua si, stability, thiab nqi-zoo piv rau cov ntshiab platinum los yog iridium-raws li anodes.
Nickel-Based Anode: Nickel-based anodes, xws li npib tsib xee lossis npib tsib xee alloys, qee zaum ua haujlwm hauv brine electrolysis. Cov anodes no muaj kev tiv thaiv zoo rau corrosion nyob rau hauv ib puag ncig chloride thiab muaj cov khoom txaus siab catalytic rau chlorine evolution.
Hlau Oxide Anodes: Qee cov hlau oxides anodes, xws li lead dioxide (PbO2) lossis ternary hlau oxides, kuj tuaj yeem siv rau hauv brine electrolysis. Cov anodes no muab kev ua haujlwm siab rau cov roj chlorine thiab ua kom muaj kev ruaj ntseg zoo.
Cov kev xaiv ntawm cov khoom tsim nyog anode rau cov brine electrolysis nyob ntawm seb tam sim no ceev, cov khoom xav tau kev ua haujlwm, thiab tus nqi-ua hauj lwm zoo. Nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev cai tshwj xeeb ntawm cov txheej txheem electrolysis thiab sab laj kev lag luam cov lus qhia lossis cov kws tshaj lij los txiav txim siab cov khoom siv anode zoo rau daim ntawv thov brine electrolysis.
