Kev siv cov nickel ua npuas ncauj

Kev siv cov nickel ua npuas ncauj

1. Cov khoom siv roj teeb electrode

Feem ntau siv cov npib tsib xee ua npuas ncauj yog cov khoom siv electrode rau cov roj teeb hluav taws xob. Nickel ua npuas ncauj muaj nyob rau hauv qee yam ntawm peb cov khoom siv hluav taws xob nquag siv xws li xov tooj ntawm tes, roj teeb lub laptop, thiab tsheb kauj vab hluav taws xob. Tsis tas li ntawd, nyob rau hauv cov roj hlwb, nws yog feem ntau siv los ua ib qho electrocatalyst los txhawb cov combustion ntawm roj hlwb.

2. Kev ua tau zoo heev catalyst cab kuj

Nickel ua npuas ncauj nws tus kheej muaj qhov tshwj xeeb qhib pore qauv, thiab tseem muaj lub zog tensile zog hauv cov txheej txheem siv tiag tiag, thiab nws tuaj yeem tiv thaiv thermal shock, yog li nws kuj tseem txhim kho kev siv ntau yam hauv cov txheej txheem siv tiag tiag. Nws kuj yog feem ntau siv los ua catalyst cab kuj thiab yog dav siv nyob rau hauv lub catalyst carrier ntawm tsheb cav. Nws yog tsuas yog siv nrog kev pab los ntawm nws cov hluav taws xob conduction zog kom zoo dua pab txhawb txoj kev hloov dua siab tshiab ntawm carbon monoxide thiab hydrocarbons thaum lub cav txias pib.

3. Lim cov khoom siv

Nickel ua npuas ncauj yog cov qauv sib xyaw ua ke, thiab cov pores no kuj muab nws cov khoom siv lim dej. Hauv kev xyaum, cov khoom siv kuj tau siv dav los ua cov khoom siv lim dej, uas tuaj yeem siv los ua cov khoom sib nqus ntws los tuav cov khoom sib nqus hauv cov kua. Tsis tas li ntawd, cov khoom siv kuj tuaj yeem siv dav hauv thaj chaw ntawm hydrogen cia nruab nrab thiab cov khoom siv hluav taws xob sib hloov, thiab lwm yam. Nws daim ntawv thov tau dav thiab thaj chaw dav heev.
