Imingeni yenzwa ye-nitrogen oxide

Imekobume erhabaxa

Ngenxa yokushisa okuphezulu kwendawo yokutsha, kuphela iintlobo ezithile zezinto ezinokusebenza in situ. Uninzi lwe Hayix izixhobo zoluvo ezenziweyo zenziwe ikheramic chwetheza iioksidi zesinyithi, kunye neyona nto ixhaphakileyo yttria-zinzisiwe zirconia (YSZ), esetyenziswa ngoku kumashumi eminyaka ubudala isivamvo oxygen. I-YSZ idityaniswe kwi-ceramic eshinyeneyo kwaye iqhuba iiyoni zeoksijini (O²⁻) kubushushu obuphezulu bombhobho ongama-400 °C nangaphezulu. Ukufumana umqondiso kwi-sensor iperi ye-electrode yobushushu obuphezulu njengeentsimbi ezintle (platinum, igolide, okanye palladium) okanye ezinye ii-oxide zentsimbi zibekwe phezu komhlaba kwaye umqondiso wombane onjengokutshintsha kwamandla ombane okanye okhoyo ulinganiswa njengomsebenzi wombane. Hayix Uxinzelelo.

Uvakalelo oluphezulu kunye nokuqina okufunekayo

Amanqanaba e-NO ajikeleze i-100–2000 ppm (iinxalenye kwisigidi) kunye NO₂ 20–200 ppm kuluhlu lwe-1–10% O₂. Inzwa kufuneka ibe novakalelo kakhulu ukukhetha la manqanaba.

Imingeni ephambili ekuphuhlisweni kwenzwa kukukhetha, ukuvakalelwa, ukuzinza, ukuveliswa kwakhona, ixesha lokuphendula, umda wokubona, kunye neendleko. Ukongeza ngenxa yendawo erhabaxa yokutsha, izinga lokuhamba kwerhasi ephezulu inokupholisa inzwa etshintsha isiginali okanye inokuphelisa i-electrode ngokuhamba kwexesha kwaye umsizi amasuntswana anokuthoba izinto.

Enye yeengxaki ezinkulu ezijongene nezo zinzwa zegesi kukufuma. Impembelelo ehambelanayo kwimpendulo yesignali ixhomekeke kakhulu kuhlobo lwenzwa. Izinzwa ze-Electrochemical zikhuselekile kwisiphumo sokufuma njengoko iimolekyuli zamanzi zinceda ukulawula uxinzelelo lwe-electrolyte kodwa ukuvezwa kwexesha elide kwigesi eyomileyo kunokunciphisa ukuxinwa kwe-solvent ye-electrolyte. Isixa esiphakamileyo sobuntununtunu besiphambano siye sabonwa kwiinzwa zegesi ngenxa yokufana kwindlela yokutshintshiselana nge-electron phakathi kweegesi ekujoliswe kuzo kunye neemolekyuli zamanzi.
