Izingeniso

Ama-catalyst ensimbi ayigugu ayizinsimbi ezinhle ezisetshenziswa kakhulu embonini yamakhemikhali ngenxa yekhono lazo lokusheshisa inqubo yamakhemikhali. Igolide, i-palladium, i-platinum, i-rhodium, nesiliva ngezinye zezibonelo zezinsimbi eziyigugu. Ama-catalyst ensimbi ayigugu yilawo aqukethe izinhlayiya zensimbi eziyigugu ezisakazeke kakhulu ezisekelwe endaweni ephezulu njenge-carbon, i-silica, ne-alumina. Lawa ma-catalyst anezinhlelo eziningana ezimbonini ezahlukahlukene. I-catalyst ngayinye yensimbi eyigugu inezici ezihlukile. Lawa ma-catalyst asetshenziswa kakhulu ekusabeleni kokwenziwa kwezinto eziphilayo. Izici ezifana nesidingo esikhulayo esivela emikhakheni yokusetshenziswa kokugcina, ukukhathazeka ngemvelo kanye nemiphumela yazo yezomthetho ziqhuba ukukhula kwemakethe.

Izakhiwo zama-catalyst ensimbi eyigugu

1. Umsebenzi ophezulu kanye nokukhetha kwezinsimbi eziyigugu ekuxazululeni inkinga

Ama-catalyst ensimbi eyigugu aqukethe izinhlayiya zensimbi eyigugu ezisakazeke kakhulu ezisekelweni ezinezindawo eziphezulu ezifana nekhabhoni, i-silica, ne-alumina. Izinhlayiya zensimbi esezingeni le-nano zimunca kalula i-hydrogen ne-oxygen emkhathini. I-hydrogen noma i-oxygen isebenza kakhulu ngenxa yokumuncwa kwayo okungafani nge-d-electron evela eqoqweni lama-athomu ensimbi eyigugu.

2. Ukuzinza

Izinsimbi eziyigugu zizinzile. Azikhi kalula ama-oxide ngokushiswa. Ama-oxide ezinsimbi eziyigugu, ngakolunye uhlangothi, awazinzile. Izinsimbi eziyigugu azincibiliki kalula esixazululweni se-asidi noma se-alkaline. Ngenxa yokuqina okuphezulu kokushisa, i-catalyst yensimbi eyigugu isetshenziswe njenge-catalysts yokuhlanza igesi yokukhipha umoya ezimotweni.
