Muaj ntau qhov laj thawj rau ruthenium iridium titanium anode passivation.
a. Txheej peeling
Lub titanium ruthenium iridium titanium anode yog tsim los ntawm titanium substrate thiab ruthenium iridium titanium active txheej. Cov tshuaj tiv thaiv electrochemical nkaus xwb yog ruthenium iridium titanium active txheej. Yog hais tias lub txheej tsis ruaj khov rau lub substrate
Khoom, cais tawm ntawm titanium phaj substrate, rau qee qhov, titanium ruthenium iridium titanium anode poob nws txoj haujlwm. (Pib rau hauv crushing hom detachment, convex plab hom delamination, thiab tawg hom detachment)
b. Kev sib cais ntawm RuO2
Qhov tshwm sim ntawm txo cov pa oxygen tuaj yeem ua rau qeeb ntawm kev tsim cov oxide zaj duab xis. Thaum tag nrho cov tam sim no ceev ntawm electrolysis nce, tus nqi ntawm cov tshuaj chlorine nce ntau ntau dua li tus nqi ntawm cov pa oxygen, yog li qhov nce ntawm qhov ceev tam sim no muaj txiaj ntsig zoo rau kev txo qis cov ntsiab lus oxygen hauv chlorine. Lub titanium substrate tau txais kev kho mob ua ntej oxidation, tsim ib txheej ntawm oxide zaj duab xis ua ntej, uas tuaj yeem ua rau kom muaj zog ntawm kev sib khi ntawm ruthenium iridium titanium active txheej thiab titanium substrate, ua rau cov txheej ruaj khov thiab tiv thaiv kev sib cais thiab kev sib cais ntawm ruthenium. Txawm li cas los xij, nws tuaj yeem ua rau muaj qhov nce hauv ohmic poob ntawm ruthenium iridium titanium anode.
c. Oxide saturation
Cov txheej txheej nquag yog tsim los ntawm cov tsis muaj stoichiometric RuO2- thiab TiO2, koom nrog pawg ntawm anoxic oxides. Qhov chaw ua kom muaj tseeb rau cov tshuaj chlorine tawm tsis yog stoichiometric oxides. Qhov ntau cov oxides muaj, cov chaw ua haujlwm ntau dua muaj, thiab qhov ua haujlwm zoo dua ntawm ruthenium iridium titanium anode. Lub conductivity ntawm ruthenium iridium titanium coated anodes yog tus cwj pwm los ntawm kev tsim ntawm distorted n-hom sib xyaw crystals los ntawm tib hom siv lead ua RuO2 thiab TiO2 tom qab kev kho cua sov, nrog qee qhov chaw ua haujlwm oxygen tam sim no. Thaum cov pa oxygen vacancies tau ntim nrog oxygen, qhov overpotential sai sai, ua rau passivation.
d. Cracks nyob rau hauv lub txheej
Thaum lub sij hawm electrolysis, ecological oxygen tshiab yog tsim nyob rau hauv lub ruthenium iridium titanium anode, nrog ib co ntawm nws tawm ntawm lub interface ntawm lub active txheej thiab electrolyte, thiab ces tawm hauv lub anode nto los tsim oxygen thiab nkag mus rau hauv cov tshuaj; Vim tias muaj cov kab nrib pleb hauv cov txheej txheem nquag, thaum lwm qhov ntawm cov pa oxygen adsorbs ntawm qhov chaw anode, nws kis tau los yog txav mus los ntawm cov txheej txheem kom ncav cuag qhov sib cuam tshuam ntawm txheej txheej thiab titanium phaj substrate. Tom qab ntawd, cov pa oxygen yog chemically adsorbed rau ntawm titanium substrate nto, ua ib zaj duab xis uas tsis yog-conductive oxide (TiO2) nrog titanium, generating reverse resistance; Xwb, cov electrolyte invades los ntawm cov kab nrib pleb nyob rau hauv lub txheej, ua rau lub titanium substrate maj mam oxidize thiab corrode nyob rau hauv lub interface nrog lub ruthenium iridium titanium active txheej, ua rau lub ruthenium iridium titanium active txheej rau detach thiab ua rau cov anode muaj peev xwm ntawm iridium ruthen. titanium. Qhov kev nce hauv qhov muaj peev xwm ntxiv txhawb kev tawg ntawm txheej thiab oxidation ntawm titanium substrate
