Thaum xaiv ib tug me me molecule dej electrode, ntau yam yuav tsum tau txiav txim siab los xyuas kom meej nws cov hauj lwm zoo nyob rau hauv lub npaj daim ntawv thov. Nov yog qee qhov kev txiav txim siab tseem ceeb:
- Cov Khoom Siv Hluav Taws Xob: Xaiv cov khoom tsim nyog uas tuaj yeem ua kom muaj txiaj ntsig zoo rau cov dej oxidation lossis txo cov tshuaj tiv thaiv. Cov khoom siv hluav taws xob ntau rau dej electrolysis suav nrog cov hlau muaj txiaj ntsig zoo li platinum (Pt), iridium (Ir), thiab ruthenium (Ru), nrog rau kev hloov pauv hlau oxides thiab sulfides.2 microns iridium coated titanium mesh thiab platinum titanium mesh ua rau cov neeg siv khoom raws li hauv qab no.
2. Catalytic Activity: Cov khoom siv electrode yuav tsum muaj kev ua haujlwm siab catalytic rau lub hom phiaj dej tshuaj tiv thaiv. Qhov kev ua no tuaj yeem txhim kho los ntawm kev siv cov tswv yim tshwj xeeb doping, cov txheej txheem nanostructuring, lossis siv cov kev txhawb nqa catalyst. Xav txog qhov ua tau zoo ntawm thermodynamic thiab kinetics ntawm cov tshuaj tiv thaiv.
3. Stability thiab Durability: xyuas kom meej tias cov khoom siv hluav taws xob muaj kev ruaj ntseg zoo thiab kav ntev raws li kev ua haujlwm. Dej electrolysis cuam tshuam nrog hnyav electrochemical ib puag ncig, yog li cov khoom siv electrode yuav tsum tiv thaiv kev degradation, corrosion, thiab deg passivation kom muaj kev ua haujlwm ntev.
4. Kev txiav txim siab txog nqi: Ntsuas cov nqi ntawm cov khoom siv electrode. Cov hlau zoo li Pt thiab Ir muaj txiaj ntsig zoo tab sis kim. Xav txog lwm cov ntaub ntawv los yog cov txheej txheem catalyst uas sib npaug ntawm kev ua tau zoo thiab tus nqi, nyob ntawm seb cov ntawv thov tshwj xeeb.
5. Electrode Configuration: Txiav txim siab qhov tsim nyog electrode configuration raws li daim ntawv thov. Cov kev teeb tsa feem ntau suav nrog cov txheej txheem electrodes, mesh electrodes, lossis cov qauv peb sab xws li nanowires lossis nanotubes. Qhov kev xaiv nyob ntawm yam xws li cov kev xav tau ceev tam sim no, kev txwv kev thauj mus los loj, thiab kev yooj yim ntawm kev tsim khoom.
6. Manufacturing Scalability: Xav txog qhov ua tau ntawm kev tsim cov electrode ntawm qhov yuav tsum tau ua thiab kom muaj nuj nqis. Qee cov ntaub ntawv lossis cov txheej txheem fabrication yuav tsim nyog rau kev siv me me, thaum lwm tus yuav zoo dua rau kev tsim khoom loj.
7. Cov Lus Qhia Tshwj Xeeb rau Daim Ntawv Thov: Nkag siab txog cov kev xav tau tshwj xeeb ntawm koj daim ntawv thov. Cov khoom siv dej electrode sib txawv yuav zoo dua rau cov tshuaj tiv thaiv oxygen evolution (anodic) lossis hydrogen evolution tshua (cathodic). Xav txog yam xws li kev siv hluav taws xob, kev xaiv cov tshuaj tiv thaiv, thiab cov txheej txheem tshwj xeeb.
Nws raug nquahu kom sab laj nrog peb tus kws tshaj lij los txiav txim siab qhov tsim nyog tshaj plaws me me dej electrode rau koj daim ntawv thov tshwj xeeb. Lawv tuaj yeem muab cov lus qhia tshaj lij rau koj hauv kev yuav khoomtitanium electrodes, thiab pab xaiv cov khoom siv hluav taws xob zoo tshaj plaws thiab kev teeb tsa.
