I-CAS 1314-08-5 okuqukethwe kwensimbi 86.2% palladium oxide PdO

Ama-Catalyst ensimbi ayigugu ayizinsimbi ezinhle ezisetshenziswa kakhulu embonini yamakhemikhali ngenxa yekhono lazo lokusheshisa inqubo yamakhemikhali. Igolide, i-palladium, iplatinum, i-rhodium, nesiliva ngezinye zezibonelo zezinsimbi eziyigugu. Ama-catalyst ensimbi ayigugu yilawo ahlanganisa izinhlayiya zensimbi eziyigugu ze-nano-scale ezihlakazeke kakhulu ezisekelwa endaweni ephakeme njengekhabhoni, i-silica, ne-alumina. Lawa ma-catalyst anezinhlelo zokusebenza eziningana ezimbonini ezihlukahlukene. I-catalyst ngayinye yensimbi eyigugu inezici eziyingqayizivele. Lawa ma-catalyst asetshenziselwa ngokuyinhloko ukusabela kwe-organic synthesis. Izinto ezifana nesidingo esikhulayo esivela emikhakheni esetshenziswa ekugcineni, ukukhathazeka kwezemvelo kanye nemithelela yazo yezomthetho kuqhuba ukukhula kwemakethe.
Izakhiwo zama-catalysts ensimbi ayigugu
1.Umsebenzi ophezulu kanye nokukhethwa kwezinsimbi eziyigugu ku-catalysis
Ama-catalyst ensimbi ayigugu ahlanganisa izinhlayiya zensimbi eziyigugu ze-nano-scale ezihlakazeke kakhulu kuzisekelo ezinendawo ephezulu efana nekhabhoni, i-silica, ne-alumina. Izinhlayiya zensimbi zesikali se-nano zikhanga kalula i-hydrogen nomoya-mpilo emkhathini. I-hydrogen noma umoya-mpilo iyasebenza kakhulu ngenxa ye-adsorption yayo ye-dissociative ngokusebenzisa i-d-electron yokuphuma kwegobolondo lama-athomu ensimbi eyigugu.
2.Ukuzinza
Izinsimbi eziyigugu zizinzile. Awenzi kalula ama-oxide nge-oxidation. Ngakolunye uhlangothi, ama-oxide ezinsimbi eziyigugu awazinzile. Izinsimbi eziyigugu azincibiliki kalula ku-asidi noma kwisisombululo se-alkali. Ngenxa yokuqina okushisayo okuphakeme, isisetshenziswa sensimbi esiyigugu sisetshenziswe njengezikhuthazi zokuhlanza igesi yokukhipha umoya.
