Porous titanium daim hlau tau tshwm sim los ua cov khoom siv tseem ceeb hauv cov tshuab electrolyzer niaj hnub, vim lawv qhov sib xyaw ua ke ntawm corrosion kuj, txhua yam muaj zog, thiab kev hloov pauv ntawm cov qauv. Lub hauv paus ruaj khov ntawm titanium oxide (TiO₂) passivation khaubncaws sab nraud povtseg enables lub sij hawm ua hauj lwm nyob rau hauv aggressive electrolytes, thaum lub ntxeem tau architecture txhim kho loj hloov mus thiab cov tshuaj tiv thaiv kinetics. Los ntawm kev muab thaj chaw loj rau cov tshuaj tiv thaiv electrochemical thiab ua kom cov pa roj thiab ion thauj mus los, cov titanium porous daim hlau tsis tsuas yog txhim kho kev ua haujlwm ntawm lub cev tab sis kuj ua kom ntseeg tau ntev - lub sijhawm ua haujlwm. Cov khoom no tso lawv raws li qhov kev xaiv uas nyiam siv los ua cov khoom siv hluav taws xob, cov khoom siv tam sim no, thiab cov roj diffusion txheej hauv cov thev naus laus zis electrolyzer.
Dab tsi yog qhov zoo ntawm kev siv cov porous titanium daim hlau hauv electrolyers?
1. Zoo heev Corrosion Resistance
- Titanium ib txwm tsim cov txheej txheem oxide ruaj khov (TiO₂) ntawm nws qhov chaw, uas tiv thaiv cov electrolytes aggressive, acids, thiab alkalis feem ntau muaj nyob rau hauv dej electrolysis systems.
2. High Electrical Conductivity (nrog kev hloov kho saum npoo los yog txheej)
- Txawm hais tias cov titanium nyoos muaj qhov sib txawv me me piv rau cov hlau xws li tooj liab, nws ua tau zoo heev thaum coated nrog cov txheej txheem catalytic (xws li platinum, iridium, ruthenium oxides). Qhov no tso cai rau kev hloov pauv tam sim no thaum lub sijhawm electrolysis.
3. Porous Structure rau huab hwm coj thauj
- Cov porosity tswj tau yooj yim rau kev nkag ntawm cov pa roj (hydrogen, oxygen, lossis lwm yam khoom) thiab ions. Nws txhim kho electrolyte nkag mus, txhim kho thaj chaw cov tshuaj tiv thaiv, thiab txo cov npuas npuas thaiv.
4. Mechanical Strength thiab Stability
- Sintered ntxeem tau titanium daim hlau muaj kev ruaj ntseg zoo heev txawm tias nyob rau hauv kev kub siab, kub viav vias, los yog lub sij hawm ua hauj lwm ntev hauv electrolyzers.
5. Loj Ntog Thaj Tsam rau Kev Tawm Tsam
- Kev sib txuas ntawm qhov pore network muab thaj chaw tshwj xeeb siab, ua kom cov chaw tawm tsam muaj zog thiab txhim kho kev ua haujlwm tag nrho.
6. Biocompatibility thiab kev nyab xeeb
- Ua tsis yog- tshuaj lom thiab ruaj khov, titanium cov ntaub ntawv tsis tso cov pa phem rau hauv electrolyte, ua kom muaj kev ruaj ntseg hydrogen lossis oxygen.
