Platinum palladium ibyuma byingirakamaro ni catalizaires itunganya imyanda ikora neza, igizwe na Pt na Pd nibindi byuma byagaciro, bityo ikaba ifite ibikorwa bya catalitike cyane no guhitamo.Irashobora guhindura neza ibintu byangiza muri gaze ya gaze ikabihindura ibintu bitagira ingaruka, bityo bikagabanya imyuka yuka ya gaze kandi ikarengera ibidukikije nubuzima bwabantu twishingikirizaho.
Ibice byingenzi bigize catalizike ya platine na palladium ni ibyuma byagaciro nka platine na palladium, kandi guhitamo ibyo byuma byagaciro birihariye cyane, bitewe nuburyo bukoreshwa bwa catalizator hamwe nibisabwa na reaction ya catalitiki.Muri rusange, igipimo rusange cya platine na palladium muri platine na catalizator ya palladium ni 1: 1 cyangwa 2: 1, kandi iri gereranya rishobora kugera ku ngaruka nziza za catalitiki.Mubyongeyeho, inkunga ya cataline ya platine palladium nayo ni ingenzi cyane, igira ingaruka zikomeye kumikorere ya catalizator.Abatwara ibintu rusange ni aluminium oxyde, okiside ya silicon, yttrium oxyde, nibindi, bitanga substrate ihamye ya catalizator kandi ikagira ingaruka nziza ya catalitiki.
Uburyo busanzwe bwo gutegura platine na palladium catalizaires zirimo gutera akabariro, imvura igwa, imvura, kuvanga umubiri nibindi.Uburyo bwo gutera akabariro ni ugutera inda itwara nabi (ubusanzwe ni oxyde) mubisubizo birimo platine na palladium, hanyuma bigakorerwa ibikorwa byinshi nko gukama no kugabanya, hanyuma ukabona cataline ya platine na palladium.Uburyo bwa coprecipitating ni uko umutwara mubi na platine na palladium ion byongewe kuri sisitemu yo kubyitwaramo hamwe, hamwe na ion ya platine na palladium bigwa hamwe hejuru yubuso bubi kugirango bibe umusemburo wa platine na palladium mugenzura agaciro ka pH na ubushyuhe bwumuti.Cataline ya platine palladium yabonetse muri ubu buryo ifite ibiranga ibikorwa byinshi, guhitamo byinshi no guhagarara neza, ibyo bigatuma imikorere n’umutekano bitunganya imyanda.
Mugihe dukoresha platine na palladium ibyuma byingirakamaro, tugomba kwitondera ibibazo byumutekano.Mbere ya byose, ni ngombwa kwirinda ibintu biteye akaga nk'umuriro ufunguye, ubushyuhe bwinshi n'amashanyarazi ahamye, ibyo bikaba bishobora gutuma imikorere mibi ya catalizator ndetse n'akaga.Icya kabiri, catalizator igomba kugenzurwa no gusimburwa buri gihe kugirango irebe imikorere yayo isanzwe kandi igere ku ngaruka nziza ya catalitiki.
