cas 10139-58-9 isisombululo esinsundu se-rhodium nitrate
Okuqukethwe kwensimbi okuqondile kwasefekthri 18.5% cas 32005-36-0 icrystal bis emnyama onsomi(dibenzylideneacetone) palladium
Izingeniso
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 aqukethe 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 ezihlukile.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 yegobolondo 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-alkaline.Ngenxa yokuqina okushisayo okuphakeme, isisetshenziswa sensimbi esiyigugu sisetshenziswe njengezikhuthazi zokuhlanza igesi yokukhipha umoya.
