Multi-stock 98% ubunyulu 16921-30-5 orenji umgubo omthubi potassium hexachloroplatinate (iv)
Iintshayelelo
Izixhobo zentsimbi ezixabisekileyo ziziintsimbi ezibekekileyo ezisetyenziswa kakhulu kwishishini lemichiza ngenxa yokukwazi kwazo ukukhawulezisa inkqubo yeekhemikhali.Igolide, ipalladium, iplatinam, irhodium, kunye nesilivere yeminye yemizekelo yeentsimbi ezixabisekileyo.Izixhobo zentsimbi ezixabisekileyo zezo ziquka i-nano-scale yexabiso lentsimbi enqabileyo yamasuntswana axhaswa kwindawo ephakamileyo njengekhabhoni, i-silica, kunye ne-alumina.Ezi catalysts zinezicelo ezininzi kumashishini ahlukeneyo.Isixhobo ngasinye sentsimbi esixabisekileyo sineempawu ezizodwa.Ezi catalysts zisetyenziswa ikakhulu kwi-organic synthesis reactions.Izinto ezinje ngokukhula kwemfuno evela kumacandelo okusetyenziswa kokuphela, iinkxalabo zokusingqongileyo kunye neziphumo zabo zomthetho ziqhuba ukukhula kwemarike.
Iipropati ze-catalysts zentsimbi ezixabisekileyo
1.Umsebenzi ophezulu kunye nokukhethwa kweentsimbi ezixabisekileyo kwi-catalysis
Izixhobo zentsimbi ezixabisekileyo zibandakanya i-nano-scale yentsimbi exabisekileyo esasazeke kakhulu kwiinkxaso ezinomgangatho ophezulu wekhabhoni, i-silica, kunye ne-alumina.Amasuntswana esinyithi esikali se-nano abhengeza ngokulula i-hydrogen kunye neoksijini emoyeni.Ihydrogen okanye ioksijini iyasebenza kakhulu ngenxa adsorption yayo dissociative ngokusebenzisa d-electron of ngaphandle kweqokobhe leathom zentsimbi exabisekileyo.
2.Uzinzo
Iintsimbi ezixabisekileyo zizinzile.Ayenzi lula iioksidi nge-oxidation.Iioksidi zesinyithi ezixabisekileyo, kwelinye icala, azinzanga.Iintsimbi ezixabisekileyo azinyibiliki lula kwi-asidi okanye kwisisombululo sealkaline.Ngenxa yozinzo oluphezulu lwe-thermal, i-catalyst yentsimbi exabisekileyo isetyenziswe njengezixhobo zokucoca igesi ephuma kwiimoto.
