I-catalyst yensimbi enegwebu inezinzuzo zokucima ukukhanya okusheshayo, usayizi omncane, amandla aphezulu kanye nokumelana nokushisa okuhle. Insimbi enegwebu iyona esetshenziswa kakhulu ekuhlanzeni imfucuza yezithuthuthu. Ifakwe ngaphambili ebusweni besithwali sensimbi esinegwebu, futhi ungqimba olushintshayo lukhiqizwa phakathi kwesithwali sensimbi esinegwebu kanye nenamathela esebenzayo ukuze kuxazululwe ukunwebeka okushisayo okuhambisana nokuguquka kwegradient phakathi kwezinto zensimbi nokunameka okusebenzayo, futhi isendlalelo soguquko siyambozwa. nge-Ce Yenziwe ngezingubo ezisebenzayo zezinto ezingavamile zomhlaba ezifana ne-La, Pr, njll., bese ilayishwa izingxenye ezisebenzayo eziqukethe izinsimbi eziyigugu njenge-Pt. kanye no-Rh. Ubuso besithwali siphathwa ukuze senze isendlalelo soguquko, futhi ukuqina okubophayo kokugqoka kuhle; ukusetshenziswa kwezinto eziphikisana nokushisa okuphezulu endaweni ephezulu, i-catalyst inokusebenza okuhle kokumelana nokushisa okuphezulu; isilinganiso sezinsimbi eziyigugu kanye nezakhi zomhlaba ezingavamile ziyathuthukiswa, futhi izinga lokushisa lokukhanya kwe-catalyst liphansi; isitoreji esisebenza kahle kakhulu Ifomula yezinto ze-oksijini, ukuhlanzeka okuphezulu kokuguquguquka kwe-catalytic; imishini enamathela othomathikhi efanelekayo othwala izinyosi metal, enamathela okuhle ukufana; impilo ende yesevisi ye-metal catalytic converter: izimoto zikaphethiloli zingafinyelela ngaphezu kwe-80,000 km; ukulawulwa kwekhwalithi okuqinile nokuhlolwa, ikhwalithi yomkhiqizo izinzile; amafomula anezindleko ezihlukene ayatholakala, futhi ukukhishwa kusezingeni elifanele kuyilapho kucatshangelwa umnotho.

Izinzuzo zensimbi yegwebu ngaphezu kwe-ceramics yezinyosi:
1. Insimbi ye-Foam inezici zensimbi, ezingakhubazeka futhi zimelane nokushaqeka, okuthuthukisa kakhulu impilo yesevisi yesiguquli se-catalytic yezindlela ezintathu zegesi yemoto kanye nesithuthuthu.
2. Ukumelana nokushisa okuphezulu kanye nokumelana nokushisa okushisayo kwensimbi enegwebu kungcono kunaleyo ye-ceramics enegwebu.
3. Isakhiwo esiyingqayizivele se-three-dimensional through-hole segwebu lensimbi sinendawo yangaphakathi enkulu ngevolumu yeyunithi kanye nomthelela ongcono wokuhlunga.
