Platinum palladium precious metal catalyst ke sesebelisoa se sebetsang hantle sa pheko ea khase ea litšila, se entsoe ka Pt le Pd le lirafshoa tse ling tsa bohlokoa, kahoo e na le ts'ebetso e phahameng haholo ea matla le khetho.E ka khona ho fetola lintho tse kotsi ka har'a khase ea mouoane 'me ea li fetola lintho tse se nang kotsi, kahoo e fokotsa ho tsoa ha khase ea mouoane le ho sireletsa tikoloho le bophelo bo botle ba batho boo re itšetlehileng ka bona.
Likarolo tsa mantlha tsa polatinamo le li-catalyst tsa palladium ke litšepe tsa bohlokoa joalo ka platinum le palladium, 'me khetho ea litšepe tsena tsa bohlokoa e ikhethile haholo, ho ipapisitse le maemo a ts'ebeliso ea sesebelisoa le litlhoko tsa karabelo ea matla.Ka kakaretso, karo-karolelano ea boima ba platinum le palladium ka platinum le palladium catalysts ke 1: 1 kapa 2: 1, 'me karo-karolelano ena e ka finyella phello e ntle ka ho fetisisa ea catalytic.Ho phaella moo, ts'ehetso ea platinum palladium catalyst e boetse e bohlokoa haholo, e nang le tšusumetso e kholo mosebetsing oa ts'ebetso.Bajari ba tloaelehileng ke aluminium oxide, silicon oxide, yttrium oxide, joalo-joalo, e fanang ka substrate e tsitsitseng bakeng sa catalyst le ho netefatsa hore ho na le phello e matla haholo ea catalytic.
Mekhoa e tloaelehileng ea ho itokisa ea li-catalysts tsa platinum le palladium e kenyelletsa ho kenngoa ha metsi, ho kopana le pula, pula, ho kopanya 'mele joalo-joalo.Mokhoa oa ho kenya letsoho ke ho kenya mokelikeli o mobe (hangata e leng oxide) ka tharollo e nang le li-ion tsa platinum le palladium, ebe o etsa letoto la ts'ebetso e kang ho omisa le ho fokotsa, 'me qetellong o fumane platinum le palladium catalyst.The coprecipitating mokhoa ke hore negative carrier le platinum le palladium ion li eketsoa tsamaisong ea karabelo hammoho, 'me li-ion tsa platinum le tsa palladium li potlakisoa hammoho holim'a sejari se fosahetseng ho theha platinum le palladium catalyst ka ho laola pH boleng le mocheso oa tharollo.Sehlahisoa sa platinum palladium se fumanoeng ka mokhoa ona se na le litšobotsi tsa mosebetsi o phahameng, khetho e phahameng le botsitso bo phahameng, e leng se tiisang katleho le polokeho ea phekolo ea khase ea litšila.
Ha re sebelisa li-catalyst tsa tšepe tsa bohlokoa tsa platinum le palladium, re lokela ho ela hloko litaba tsa polokeho.Pele ho tsohle, hoa hlokahala ho qoba maemo a kotsi a kang lelakabe le bulehileng, mocheso o phahameng le motlakase o tsitsitseng, e leng se ka lebisang ho senyeha ha ts'ebetso ea catalyst esita le kotsi.Taba ea bobeli, catalyst e hloka ho hlahlojoa le ho nkeloa sebaka khafetsa ho netefatsa ts'ebetso ea eona e tloaelehileng le ho fihlela phello e ntle ka ho fetisisa ea catalytic.
