Isethulo
Ama-catalysts wensimbi ayigugu ayizinsimbi ezinhle ezisetshenziswa kabanzi embonini yamakhemikhali ngenxa yenqubo yawo yokusheshisa inqubo yamakhemikhali. Igolide, i-palladium, iplatinamu, i-rhodium, nesiliva kungenye yezibonelo zezinsimbi eziyigugu. Ama-catalysts wensimbi ayigugu yilawo aqukethe izinhlayiya zensimbi ezihlakazekile kakhulu ze-nano-scale eziyigugu ezisekelwe endaweni ephezulu ephakeme njengekhabhoni, i-silica, kanye ne-alumina. Lawa ma-catalysts anezicelo eziningi ezinhlobonhlobo zezimboni. I-catalyst yensimbi ngayinye eyigugu inezimpawu ezihlukile. Lawa ma-catalysts asetshenziselwa ukusabela kwe-organic synthesis. Izici ezinjengokukhula kwesidingo esivela emikhakheni yokusebenzisa ekugcineni, ukukhathazeka kwemvelo kanye nemiphumela yabo yezomthetho ishayela ukukhula kwemakethe.
Izakhiwo zama-catalysts wensimbi ayigugu
Umsebenzi we-1.High kanye nokukhetha kwezinsimbi eziyigugu eCatalysis
Ama-catalysts wensimbi ayigugu aqukethe izinhlayiya zensimbi ezihlakazekile ze-nano-esilinganiselwe kakhulu ezisekelweni ezisekelwa yindawo ephezulu enjengekhabhoni, i-silica, kanye ne-alumina. Izinhlayiya ze-Nano ezilinganiswa kalula i-adsorb hydrogen nomoya-mpilo emoyeni. I-hydrogen noma i-oxygen isebenza kakhulu ngenxa ye-adsorption yayo eyinqaba nge-D-electron of ngaphandle kwe-Shell yama-athomu wensimbi ayigugu.
2.I-
Izinsimbi eziyigugu zizinzile. Abakha kalula ama-oxides nge-oxidation. Ngakolunye uhlangothi, ama-oxides wezinsimbi eziyigugu akhona, akusizinzile. Izinsimbi eziyigugu azincibiliki kalula kwikhambi le-acid noma i-alkali. Ngenxa yokuqina okuphezulu okushisayo, i-catalyst yensimbi eyigugu isetshenzisiwe njengama-catalysts e-temotive ackopive actifish catalysts.
