Cov khoom tseem ceeb ntawm ozone kev puas tsuaj catalysts

Cov khoom tseem ceeb ntawm ozone decomposition catalysts feem ntau suav nrog cov sib txuas ntawm kev hloov pauv hlau oxides (xws li manganese, tooj liab, hlau, cobalt, thiab npib tsib xee), cov hlau zoo (xws li platinum thiab palladium), thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb (xws li cerium thiab lanthanum). Cov khoom no tsim cov tshuab catalytic zoo heev los ntawm kev txhawb nqa ntawm cov nqa khoom (xws li cov pa roj carbon activated, molecular sieves, alumina, lossis titanium dioxide).

Core Active Cheebtsam

• Kev hloov pauv hlau oxides: Manganese oxide (MnO₂) yog qhov feem ntau ozone decomposition catalyst, muab cov nqi qis thiab kev ua haujlwm siab; tooj liab oxide (CuO) thiab hlau oxide (Fe₂O₃) yog haum rau tej thaj chaw pH.
• Noble Metals: Platinum (Pt) thiab palladium (Pd) muaj kev ua haujlwm siab catalytic tab sis kim heev, thiab feem ntau yog siv rau hauv kev kho mob lossis siab - daim ntawv thov kom huv.
• Tsis tshua muaj Lub Ntiaj Teb Elements: Cerium (Ce) qhov sib txawv valence zog txhim kho nws cov peev xwm redox thiab nws feem ntau siv ua ke nrog lwm cov hlau.

Cov khoom siv thauj khoom

• Activated Carbon: Muab thaj chaw siab tshwj xeeb tab sis yooj yim oxidized thiab depleted los ntawm ozone.
• Molecular sieves: Txhim kho ozone tiv taus kev ua haujlwm los ntawm cov pores tsis tu ncua thiab nthuav tawm cov dej tsis zoo.

Cov khoom pab cuam

• Binders (xws li silica sol) yog siv los immobilize lub active Cheebtsam.
• Co-cov catalysts (xws li tungstates) tuaj yeem tswj hwm tus nqi hloov hluav taws xob.
