Dab tsi yog qhov zoo tshaj plaws hlau siv rau electrolysis dej?

Electrolysis ntawm dej, yog kom dhau tam sim no los ntawm cov dej los tsim hydrogen thiab oxygen. Roj hlwb siv hydrogen ua roj. Hydrogen yuav siv los ua lub zog tsheb hauv lub neej yav tom ntej, txo cov pa phem, txhim kho kev siv hluav taws xob, txuag hluav taws xob.

Ntshiab titanium, piv rau stainless hlau thiab titanium alloys, yog ib qho kev xaiv zoo heev rau daim ntawv thov no vim nws lub zog siab, corrosion kuj, thiab hluav taws xob conductivity.

Dej electrolysis yog tib txoj hauv kev ua kom hydrogen los ntawm dej. Cov dej electrolysis muaj ob qhov kev tshwm sim ib nrab: cov tshuaj tiv thaiv cathodic hydrogen evolution, cov tshuaj tiv thaiv anodic oxygen evolution, thiab txo cov tshuaj tiv thaiv.

Cov hlau hloov pauv yog titanium. Nws muaj cov cim tshuaj Ti thiab tus lej atomic 22. Nws belongs rau IVB hlau element pawg ntawm daim ntawv teev sijhawm.

Titan muaj qhov melting point ntawm 1660 degree, qhov kub ntawm 3287 degree thiab qhov ntom ntawm 4.54g / cm³. Nyob rau xyoo 1971, nws tau pom los ntawm William Gregor, tus kws kho tsiaj hauv tebchaws Askiv.

Ntshiab titanium, piv rau stainless hlau thiab titanium alloys, yog ib qho kev xaiv zoo heev rau daim ntawv thov no vim nws lub zog siab, corrosion kuj, thiab hluav taws xob conductivity.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov ntshiab titan hauv dej electrolysis yog nws qhov ua haujlwm siab rau corrosion. Nws yog ib qho tseem ceeb heev uas yuav tau ua qhov no thaum ua hauj lwm nrog dej ntawm siab purity los yog thaum electrolysing hydrogen gas. PureTitanium tuaj yeem tiv taus cov tshuaj hnyav ntawm cov electrolyte yam tsis muaj corroding lossis degrading dhau sijhawm. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau daim ntawv thov no.

Lwm qhov txiaj ntsig tseem ceeb ntawm kev siv titanium hauv dej molecules electrolysis yog nws cov conductivity. Lub anode thiab cathode yog ua los ntawm titanium, uas yog ib qho zoo heev conductor. Titanium lub siab conductivity tso cai rau cov hluav taws xob xa mus tau zoo ntawm electrodes. Qhov no ua rau muaj txiaj ntsig zoo ntawm electrolysis, thiab ntau dua ntawm hydrogen.

Thaum kawg, titanium yog cov hlau muaj zog tshwj xeeb, uas ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau lub zog siab thiab ua haujlwm ntev. Hauv dej electrolysis, titan yog siv los ua cov electrodes uas tuaj yeem tiv taus cov hluav taws xob siab thiab cov dej ntws uas xav tau rau kev tsim cov hydrogen.

Titanium yog ib qho khoom siv zoo rau dej electrolysis vim nws muaj kev tiv thaiv corrosion zoo heev, kev ua haujlwm siab thiab lub zog txawv tshaj plaw. Titanium yog qhov kev xaiv zoo tshaj plaws rau cov hlwb electrolytic thaum ua haujlwm nrog cov dej purity siab lossis xav tau hydrogen ntawm qhov zoo tshaj plaws.

Tib neeg kuj nug tias:

(1) Yuav ua li cas yog titanium dioxide tsim los ntawm titanium tetrachloride ticl4?

TiCl4 kua yog hydrolyzed los tsim H2TiO3, thiab titanic acid yog rhuab thiab decomposed los tsim titanium dioxide.

(2) Kev faib tawm ntawm hydrogen ntau lawm los ntawm dej electrolysis:

Dej electrolysis yog cais raws li cov khoom siv diaphragm siv hauv electrolyzer. Qhov no suav nrog alkaline dej (AE), proton-exchange membrane (PEM), thiab kub kub khoom oxide (SOEC) dej electrolysis.
