Lub titanium ntxeem tau-raws li photoanode electrolyzer rau hydrogen ntau lawm yog ib tug tshwj xeeb ntaus ntawv uas siv kev sib xyaw ntawm photoelectrochemical thiab dej electrolysis cov tswv yim los hloov lub hnub ci zog rau hydrogen gas. Lub hauv paus tseem ceeb ntawm cov electrolyzer no yog cov ntxeem tau titanium, uas ua haujlwm ua lub substrate rau lub anode. Qhov ntxeem tau ntawm titanium muaj cov yam ntxwv hauv qab no: Ib qho ntxeem tau ntawm titanium zoo li photoanode electrolyzer rau hydrogen ntau lawm yog ib qho cuab yeej tshwj xeeb uas siv kev sib xyaw ntawm photoelectrochemical thiab dej electrolysis cov tswv yim los hloov lub hnub ci zog rau hauv hydrogen gas. Lub hauv paus tseem ceeb ntawm cov electrolyzer no yog cov ntxeem tau titanium, uas ua haujlwm ua lub substrate rau lub anode.
Qhov ntxeem tau ntawm titanium muaj cov yam ntxwv hauv qab no:
Ti Felt
1. Qhov loj ntawm thaj chaw: Cov qauv ntawm cov ntxeem tau titanium muaj qhov muaj qhov porosity siab thiab thaj chaw loj, txhim kho qhov ua tau zoo ntawm lub teeb nqus thiab cov tshuaj electrochemical.
2. Kev ua tau zoo heev: Cov titanium ntxeem tau pom muaj cov khoom siv hluav taws xob zoo, ua kom yooj yim rau kev hloov ntawm electrons thiab ions los txhawb cov tshuaj tiv thaiv electrolytic.
3. Kev ruaj ntseg siab: Titanium muaj qhov ua kom pom kev tiv thaiv corrosion thiab kub kub ua haujlwm, ua kom cov qauv ruaj khov thiab ua haujlwm ntev nyob rau hauv hnyav electrolysis.
Nyob rau hauv lub teeb photoanode electrolyzer nrog ib tug ntxeem tau titanium xav substrate, lub anode yog feem ntau coated nrog lub teeb-absorbing thiab catalytically active cov ntaub ntawv xws li BiVO4 los yog lwm yam hlau oxides. Cov ntaub ntawv no nqus lub hnub ci zog thiab txhawb kev sib cais ntawm cov dej molecules, cais hydrogen ions (H^+) thiab electrons (e^-) los ntawm dej los tsim cov roj hydrogen (H2).
Los ntawm kev hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob, cov ntxeem tau titanium zoo li photoanode electrolyzer muaj peev xwm daws tau kev tsim hluav taws xob ruaj khov. Nws nta kev ua haujlwm siab, ruaj khov, thiab ib puag ncig tus phooj ywg, ua rau nws siv tau hauv thaj chaw xws li hydrogen cia thiab roj hlwb. Qhov kev siv tshuab no tsav kev siv lub zog tauj dua tshiab thiab kev nce qib ntawm hydrogen zog siv.
