What is the alloy catalyst

Bimetallic catalyst is often referred to as the alloy catalyst. In its actual form is not necessarily the alloy reaction conditions. Normally consists of active metal and noble metal alloy catalyst, it can show a kind of metal is another kind of metal dilution geometry or group effect, and electronic interaction of the ligand effect. Such as Pt catalyst after joining Sn or Re alloying, can improve the alkane dehydrogenation cyclization and aromatization activity and stability. Add Ir Pt catalyst make naphtha reforming under low pressure, and increase the heavy distillate oil generation. I add Cu Ni alloying of cyclohexane dehydrogenation activity remains unchanged, but can significantly reduce the activity of hydrogen solution of ethane.
