Research Abstract

Most Al-based quasicrystals (QCs) contain catalytically active metals such as Pd, Ni or Cu. Therefore, the catalytic properties of some QCs have been examined so far and results are found to be promising. The quasiperiodic structure of the Al-Cu-Fe QC plays an important role in the formation of a homogeneous leached layer that is responsible for the high activity and stability for steam reforming of methanol (SRM). In this study, we found that nanocrytalline Pd-TM alloys can be prepared by the selective leaching of Al from Al-Pd-TM (TM=Ni, Co) QCs. Alloying between Pd and TM occurred in a self-assembled manner during leaching process. The advantage of this method is that there is no restriction of reduction properties of the constituent metals because neither metal complexes nor metal salts were used in the process, and hence instead of core-shell structure, a homogeneous solid solution would be formed in nanoparticles.
