Electrochemical txoj kev muaj txiaj ntsig zoo rau kev kho mob ntawm cov khoom siv hluav taws xob refractory, thiab nws tuaj yeem hloov cov organic uas tsis yog biochemically degradable rau hauv biochemically degradable organic teeb meem. Lub electrochemical hloov pauv cov tshuaj tiv thaiv ntawm cov organic teeb meem feem ntau qeeb, yog li nws feem ntau txhim kho los ntawm kev ua kom cov khoom siv hluav taws xob ntau dhau, ua rau thaj tsam ntawm electrode, xaiv cov khoom siv electrode zoo, thiab txhim kho cov qauv electrode. Nyob rau hauv cov tshuaj tiv thaiv electrochemical, lub electrode deg cheeb tsam yog nrog los ntawm ib tug heterogeneous catalysis cov tshuaj tiv thaiv nrog lub zog ntawm tsub nqi, uas yog zoo ib yam li tshuaj catalysis. Nyob rau hauv ib qho electrolyte, nyob rau hauv tib lub overpotential, electrode cov tshuaj tiv thaiv tus nqi thiab cov tshuaj tiv thaiv hom hloov vim qhov sib txawv ntawm cov khoom siv electrode matrix, uas yog sau ua ke hu ua electrocatalysis hauv electrochemistry. Hauv cov tshuaj tiv thaiv electrocatalytic, raws li electrocatalysts, cov khoom siv hluav taws xob sib txawv tuaj yeem hloov cov tshuaj tiv thaiv electrochemical los ntawm kev txiav txim ntawm qhov loj. Yog li ntawd, xaiv cov khoom siv electrode tsim nyog yog ib txoj hauv kev zoo los txhim kho kev ua haujlwm ntawm electrochemical catalytic tshua.
Hauv kev kho dej, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm electrolysis ntawm dej, muaj ntau yam muaj zog oxidizing tshuaj nyob rau hauv dej, xws li: O3, H2O2, HCLO, thiab lwm yam., thiab cov anode yog feem ntau commutated, yog li ntawd nws yog tsim nyog los ua ib tug oxidizing tshuaj. siv tshwj xeeb ua haujlwm electrodes. Tom qab xyoo ntawm kev tshawb fawb,TopTechtau tsim lub neej ntev electrode haum rau kev kho dej-titanium hlau coated electrode. Cov electrode no yog coated nrog platinum pab pawg noble hlau oxide nrog siab electrocatalytic kev ua tau zoo, muaj zog tiv thaiv oxidation kev ua tau zoo thiab zoo hluav taws xob conductivity ntawm ntshiab titanium substrate, thiab yog ib tug insoluble anode. Cov khoom ntawm no anode yog:
1. Titanium muaj cov yam ntxwv ntawm lub teeb tshwj xeeb lub ntiajteb txawj nqus, lub zog zoo, corrosion kuj thiab kev ua tau zoo, tshwj xeeb tshaj yog nws tsis kam rau cov chlorine ntub dej, uas yog unmatched los ntawm lwm cov ntaub ntawv hlau. Piv txwv li, thaum muaj me me ntawm chloride ions nyob rau hauv electrolysis ntawm dej, stainless hlau phaj yuav pitted sai sai, uas yuav shorten lub neej ntawm electrode, tab sis titanium tsis muaj cov teeb meem no.
2. Vim yog qhov sib ntxiv ntawm ntau pawg platinum cov hlau muaj txiaj ntsig hauv txheej txheej, nws muaj kev ua haujlwm siab tam sim no, hluav taws xob zoo, kev ua haujlwm zoo electrocatalytic, muaj zog oxidation tsis kam, ua haujlwm ntev thiab txuag hluav taws xob.
3. Nws muaj qhov ua tau zoo ntawm kev thim rov qab.
Titanium anodeyog ib qho tseem ceeb ntawm cov dej electrolysis tshuab. Qhov zoo ntawm cov hlau electrode ncaj qha cuam tshuam qhov zoo ntawm tag nrho cov tshuab dej. Yuav ua li cas xaiv electrodes yuav tsum raug xaiv kom haum raws li qhov sib txawv ua haujlwm. Hauv kev kho dej, hlau electrodes yuav tsum muaj cov hauv qab no:
1. Muaj hluav taws xob conductivity zoo.
2. Muaj zog corrosion kuj.
3. Zoo mechanical zog thiab kev ua tau zoo.
4. Lub neej ua haujlwm ntev.
5. Muaj kev ua haujlwm zoo electrocatalytic, thiab lwm yam.
Hauv cov tshuaj tiv thaiv electrochemical, ntau cov khoom siv hluav taws xob kuj yog ib qho kev tshawb fawb tseem ceeb. Kev npaj ntawm Ti / SnO2 · Sb203 "MnO2 / Pb02 · MnO2 anode tuaj yeem siv los ua piv txwv ntawm ntau cov khoom siv hluav taws xob tsim.titanium anodeyog tias cov pa tshiab ecological tsim los ntawm cov pa oxygen evolution cov tshuaj tiv thaiv diffuses rau saum npoo ntawm electrode, yog li tsim ib zaj duab xis uas tsis yog-conductive TiO2. Txhawm rau qhib lub anode, ib txheej ntawm PbO2·MnO2 active txheej yog ntxiv rau saum npoo ntawm electrode; Txhawm rau kom txo tau qhov sib txawv ntawm cov pa oxygen tshiab rau titanium nto, ib txheej ntawm SnOz·Sb203 ntxiv ntawm titanium anode substrate thiab cov txheej txheem nquag. · MnO2 nruab nrab txheej. Lub anode muaj kev ua haujlwm siab electrocatalytic thiab electrochemical stability hauv kev kho cov dej khib nyiab phenolic.
