Gabatarwa
Ƙarfe masu daraja ƙarfe ne masu daraja da ake amfani da su a masana'antar sinadarai saboda iyawarsu na hanzarta aiwatar da sinadarai.Zinariya, palladium, platinum, rhodium, da azurfa wasu misalan karafa ne masu daraja.Ƙarfe masu daraja sune waɗanda suka ƙunshi tarwatsewar ɓangarorin ƙarfe masu daraja na Nano-sikelin da aka goyan bayan wani babban fili kamar carbon, silica, da alumina.Waɗannan masu haɓakawa suna da aikace-aikace da yawa a cikin masana'antu iri-iri.Kowane karfe mai daraja yana da halaye na musamman.Ana amfani da waɗannan abubuwan haɓakawa da farko don haɓakar halayen halitta.Abubuwa kamar haɓaka buƙatu daga sassan amfani da ƙarshen, matsalolin muhalli da tasirinsu na doka suna haifar da haɓakar kasuwa.
Properties na daraja karfe catalysts
1.High aiki da selectivity na daraja karafa a catalysis
Ƙarfe masu daraja sun ƙunshi ɓarke nano-sikelin ƙarfe masu tamani sosai akan goyan bayan yanki mai tsayi kamar carbon, silica, da alumina.Nano sikelin karfe barbashi sauƙi adsorb hydrogen da oxygen a cikin yanayi.Hydrogen ko oxygen yana aiki sosai saboda rarrabawar sa ta hanyar d-electron daga harsashi na atom ɗin ƙarfe masu daraja.
2. Kwanciyar hankali
Ƙarfe masu daraja suna da ƙarfi.Ba su da sauƙi su samar da oxides ta hanyar oxidation.Oxides na karafa masu daraja, a gefe guda, ba su da kwanciyar hankali.Ƙarfe masu daraja ba sa narkewa cikin sauƙi a cikin maganin acid ko alkaline.Saboda tsayin daka na yanayin zafi, an yi amfani da karfen ƙarfe mai tamani azaman abubuwan haɓaka iskar gas mai fitar da hayaki.
