GG quot; peb-txoj kev" nyob rau hauv peb-txoj kev hloov catalytic hais txog peb yam tsis tshua muaj nqi thiab muaj nqi hlau uas muaj nyob hauv cov catalyst txheej: platinum (pt), rhodium (Rh), thiab palladium (pd), thaum lub tshuab catalyst cov khoom siv ntawm no yog rhodium nitrate, palladium nitrate thiab platinum nitrate.
Yog vim li cas vim li cas tus nqi ntawm peb-txoj kev hloov catalytic yog kim heev yog tias cov hlau tsis tshua muaj nqi muaj nyob hauv no" peb-txoj kev" yog ib qho ntawm cov laj thawj. Txawm li cas los xij, qhov ntau ntawm cov khoom siv tsis tshua muaj hlau nyob hauv peb-txoj kev hloov catalytic tam sim no tsawg zuj zus lawm.
Hauv cov txheej txheem kev ua kom huv cov roj, platinum (Pt) thiab palladium (Pd) mas catalyze cov pa roj carbon monoxide thiab hydrocarbons, thaum rhodium (Rh) mas catalyzes nitrogen oxides. Cov duab pob zeb ceramic yog honeycomb-puab, uas tuaj yeem nce ntau qhov peb catalytic qhov chaw hloov chaw ntawm catalytic converter.
