Nano platinum (Pt) bakeng sa thuso ea litsela tse tharo kalafong ea mosi oa koloi

The Three-way Catalyst ke mokelikeli o sebelisitsoeng ho feto-fetoha ha mekhoa e meraro ea mosi oa koloi. E sebelisoa ho fetolela mosi oa koloi pele o tsoa, ​​le ho oxidize CO, HC, le NOx ka ho latellana, ho fokotsa likhase tse kotsi ho carbon dioxide (CO2), nitrogen (N2), le mouoane oa metsi (H2O) tse se nang kotsi ho motho. bophelo bo botle.
Pt ke karolo ea pele ea matla e sebelisoang ho hloekisa mosi oa koloi. Monehelo oa eona o ka sehloohong ke phetoho ea carbon monoxide le hydrocarbon. Pt e na le bokhoni bo itseng ba ho fokotsa nitrogen monoxide, empa ha NO ea mahloriso e phahame kapa SO2 e le teng, ha e sebetse joaloka Rh, le platinum nanoparticles (NPs) e tla sinter ka nako. Kaha polatinamo e tla kopana kapa e fokotsehe mochesong o phahameng, le eona e tla fokotsa ts'ebetso e akaretsang ea matla. Liphuputso li tiisitse hore liathomo tsa tšepe tsa sehlopha sa platinum li ka fapanyetsanoa pakeng tsa li-nanoparticles tsa tšepe le matrix a perovskite a mangata, kahoo a tsosolosa mosebetsi oa catalytic.
Litšepe tsa bohlokoa li na le khetho e ntle haholo ea catalytic. Ho na le litlamorao tse batlang li rarahane kapa litlamorao tsa synergistic lipakeng tsa lirafshoa tsa bohlokoa le lipakeng tsa lirafshoa tsa bohlokoa le bahlahisi. Metsoako e fapaneng ea tšepe ea bohlokoa, likarolelano le mahlale a ho jarolla li na le tšusumetso e kholo sebopehong sa bokaholimo, sebopeho sa bokaholimo, ts'ebetso ea catalytic le khanyetso e phahameng ea mocheso oa sintering ea catalyst. Ntle le moo, mekhoa e fapaneng ea ho eketsa batšehetsi le eona e tla ba le tšusumetso e itseng ho mokelikeli. Moloko o mocha oa Pt-Rh-Pd ternary catalysts o entsoe ka ho sebelisa tšebelisano e sebetsang pakeng tsa Pt, Rh le Pd, e leng se ntlafalitseng haholo ts'ebetso ea ts'ebetso.
