Nyob rau hauv daim ntawv no, daim ntawv thov ntawm titanium nitride carbonitride nyob rau hauv ib puag ncig tswj kev ua qias tuaj thiab nws cov txheej txheem cuam tshuam yuav raug qhia kom ntxaws.

Ua ntej tshaj plaws, titanium nitride plays lub luag haujlwm tseem ceeb hauv kev tswj huab cua. Atmospheric pollution yog ib qho teeb meem loj uas ntsib cov neeg tam sim no, uas cov pa phem tseem ceeb suav nrog sulfur dioxide, nitrogen oxides thiab volatile organic compounds. Raws li cov khoom siv photocatalytic muaj txiaj ntsig, titanium nitride carbide tuaj yeem siv lub hnub ci lossis cov teeb pom kev zoo los txhawb nws cov neeg nqa khoom thiab ua tiav cov tshuaj tiv thaiv redox los ntawm cov tshuaj tiv thaiv ntawm photogenerated electrons thiab qhov. Siv titanium nitride carbonate catalysts, cov khoom tsis zoo xws li sulfur dioxide, nitrogen oxides thiab volatile organic tebchaw nyob rau hauv cov huab cua tuaj yeem catalytically oxidized rau hauv cov khoom tsis zoo, yog li txo qis cov pa phem. Tsis tas li ntawd, titanium carbonitride catalyst tseem tuaj yeem txo cov kev siv photocatalyst thiab tus nqi ntawm catalyst, muab cov tshuaj tshiab rau kev tswj huab cua.

Thib ob, titanium nitride carbide kuj tau siv dav hauv kev tswj dej paug. Dej muaj kuab paug yog ib qho teeb meem loj uas tau ntsib hauv ntiaj teb, uas cov pa phem tseem ceeb suav nrog cov hlau hnyav ions, cov pa phem organic thiab cov kab mob. Titanium carbonitride muaj kev ua haujlwm siab photocatalytic thiab pom lub teeb pom kev zoo, uas tuaj yeem siv tag nrho cov hnub ci lossis pom lub teeb rau photocatalytic degradation ntawm cov teeb meem hauv dej. titanium nitride photocatalysis tuaj yeem ua rau cov decomposition ntawm cov pa phem hauv dej rau hauv cov pa roj carbon dioxide thiab dej, thiab hloov cov hlau hnyav ions mus rau hauv cov dej tsis zoo lossis me ntsis soluble precipitates los ntawm lub teeb adsorption thiab photocatalytic txo. Tsis tas li ntawd, titanium nitride carbonate kuj tuaj yeem tua cov kab mob hauv dej, xws li cov kab mob thiab cov kab mob, thiab ntxuav cov dej. Yog li ntawd, titanium nitride carbonate muaj ib tug dav daim ntawv thov kev cia siab nyob rau hauv dej muaj kuab paug tswj.
Daim ntawv thov ntawm titanium nitride nyob rau hauv ib puag ncig muaj kuab paug tswj yog ze ze rau nws photocatalytic mechanism. Titanium nitride tuaj yeem nqus tau ntau yam ntawm lub teeb pom kev, thiab nws cov qauv siv hluav taws xob ua rau nws cov khoom siv hluav taws xob thiab qhov nkag mus rau saum npoo ntawm cov khoom thiab ua rau cov pa oxygen molecules los yog dej molecules adsorbed rau saum npoo. Photogenerated electrons tuaj yeem txo cov teeb meem xws li cov hlau hnyav ions thiab nitrogen oxides, thaum lub qhov photogenerated tuaj yeem oxidize cov pa phem thiab tua cov kab mob. Tsis tas li ntawd, vim lub siab electron khi zog thiab redox lub peev xwm ntawm titanium nitride carbide, nws muaj lub neej ntev rau cov neeg nqa khoom photogenerated, uas txhim kho kev ua haujlwm ntawm cov tshuaj tiv thaiv photocatalytic.

Hauv kev siv cov tswv yim, cov haujlwm photocatalytic thiab kev ruaj ntseg ntawm titanium nitride carbide feem ntau nyob ntawm nws cov qauv thiab cov khoom. Feem ntau hais lus, cov haujlwm photocatalytic ntawm titanium nitride carbide yog ze ze rau nws qhov chaw morphology, siv lead ua qauv thiab cov pab pawg ua haujlwm. Piv txwv li, qhov chaw morphology muaj ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm lub teeb nqus thiab lub teeb pom kev zoo, thiab titanium nitride carbonitride nrog nanoparticle thiab lamellar qauv muaj qhov loj dua qhov chaw tshwj xeeb thiab ntau qhov chaw ua haujlwm, uas txhim kho cov haujlwm photocatalytic. Tsis tas li ntawd, doping lossis hloov kho cov qauv siv lead ua thiab cov pab pawg ua haujlwm ntawm titanium nitride carbide tuaj yeem tswj hwm nws cov qauv siv hluav taws xob thiab hluav taws xob khi lub zog, uas cuam tshuam rau nws cov kev ua haujlwm photocatalytic. Yog li, kev xaiv cov khoom tsim nyog titanium nitride carbide thiab kev hloov kho ntawm lawv cov qauv thiab cov khoom hauv daim ntawv thov yog tus yuam sij kom paub txog kev tswj hwm ib puag ncig muaj kuab lom.

Hauv kev xaus, titanium nitride carbide, ua ib yam tshiab ntawm cov khoom siv photocatalytic, plays lub luag haujlwm tseem ceeb hauv kev tswj hwm ib puag ncig. Nws tuaj yeem degrade cov khoom tsis zoo hauv cov huab cua thiab dej los ntawm cov tshuaj tiv thaiv photocatalytic thiab ua kom huv ib puag ncig. Kev ua haujlwm photocatalytic thiab kev ruaj ntseg ntawm titanium nitride yog ze ze rau nws cov qauv thiab cov khoom, yog li nws yuav tsum xaiv cov ntaub ntawv titanium nitride uas tsim nyog thiab tswj nws cov qauv thiab cov khoom los txhim kho cov nyhuv photocatalytic hauv kev siv tswv yim. Nrog rau kev txhawb nqa ntxiv ntawm lub tswv yim ntsuab, peb ntseeg tias daim ntawv thov ntawm titanium carbonitride hauv kev tswj hwm ib puag ncig yuav nthuav dav ntxiv.
