Masu haɓaka ƙarfe masu daraja ƙarfe ne masu daraja da ake amfani da su sosai a masana'antar sinadarai saboda ikonsu na hanzarta aiwatar da sinadarai. Zinariya, palladium, platinum, rhodium, da azurfa wasu daga cikin misalan ƙarfe masu daraja ne. Masu haɓaka ƙarfe masu daraja su ne waɗanda suka ƙunshi ƙwayoyin ƙarfe masu daraja masu yawan nano waɗanda aka tallafa musu a babban yanki kamar carbon, silica, da alumina. Waɗannan masu haɓaka ƙarfe suna da aikace-aikace da yawa a cikin masana'antu daban-daban. Kowane mai haɓaka ƙarfe mai daraja yana da halaye na musamman. Ana amfani da waɗannan masu haɓaka ƙarfe galibi don halayen haɗakar halitta.

Kayayyakin ƙarfe masu daraja masu kara kuzari
1. Babban aiki da zaɓin ƙarfe masu daraja a cikin catalysis
Masu haɓaka ƙarfe masu daraja sun ƙunshi ƙwayoyin ƙarfe masu daraja masu yawan nano a kan tallafi masu girman saman kamar carbon, silica, da alumina. Ƙwayoyin ƙarfe masu sikelin nano suna shakar hydrogen da oxygen cikin sauƙi a cikin sararin samaniya. Hydrogen ko oxygen yana aiki sosai saboda shaƙarsa ta hanyar d-electron daga cikin harsashi na ƙwayoyin ƙarfe masu daraja.
2. Kwanciyar hankali
Karafa masu daraja suna da karko. Ba sa samar da iskar oxygen cikin sauƙi ta hanyar iskar oxygen. A gefe guda kuma, iskar oxygen na karafa masu daraja ba ta da karko sosai. Karafa masu daraja ba sa narkewa cikin sauƙi a cikin ruwan acid ko alkaline. Saboda yawan kwanciyar hankali na zafi, an yi amfani da mai kara kuzari na karafa masu daraja a matsayin mai kara kuzari na tsarkake iskar gas ta mota.
