Nano platine (Pt) kubintu bitatu byifashishwa mu kuvura ibinyabiziga
Inzira eshatu zitanga umusemburo ukoreshwa muburyo butatu bwa catalitike ihindura ibinyabiziga. Ikoreshwa muguhindura catalitike yimyuka yimodoka mbere yuko isohoka, no okiside CO, HC, na NOx, kugabanya imyuka yangiza kuri dioxyde de carbone (CO2), azote (N2), hamwe numwuka wamazi (H2O) utagira ingaruka kubantu. ubuzima.
Pt nigice cyambere cya catalitiki ikora ikoreshwa mugusukura imodoka. Umusanzu wacyo nyamukuru ni uguhindura monoxyde de carbone na hydrocarbone. Pt ifite ubushobozi bwo kugabanya monoxide ya azote, ariko mugihe OYA yibanze cyane cyangwa SO2 ihari, ntabwo ikora neza nka Rh, kandi platine nanoparticles (NPs) izacumura mugihe runaka. Kubera ko platine izateranya cyangwa igabanuke ku bushyuhe bwinshi, nayo izagabanya ibikorwa rusange bya catalitiki. Ubushakashatsi bwemeje ko atome yo mu matsinda ya platine ishobora guhanahana hagati ya nanoparticles yicyuma na matrike ya perovskite, bityo igakora ibikorwa bya catalitiki.
Ibyuma by'agaciro bifite amahitamo meza ya catalitiki. Hano haribintu bigoye guhuza ingaruka cyangwa guhuza imbaraga hagati yamabuye y'agaciro no hagati y'ibyuma byagaciro na promoteri. Ibikoresho bitandukanye by'agaciro bihujwe, ibipimo hamwe na tekinoroji yo gupakira bigira uruhare runini mubuso bwubuso, imiterere yubuso, ibikorwa bya catalitiki hamwe nubushyuhe bwo hejuru bwo gucana kwa catalizator. Mubyongeyeho, uburyo butandukanye bwo kongerera abamamaza nabo bizagira ingaruka runaka kuri cataliste. Igisekuru gishya cya Pt-Rh-Pd catalizator cyatejwe imbere hifashishijwe guhuza ibikorwa hagati ya Pt, Rh na Pd, byateje imbere imikorere ya catalizator.
