Abstract

Catalytic properties of the metal foils were tuned by the specific surface crystallographic orientation control. The NO + CO reactivity of polycrystalline Pd foils with (101) or (211) orientation, characterized by using electron backscattered diffraction (EBSD), was investigated. The (211)-oriented Pd foils exhibited much greater activity compared with (101) orientated Pd foils, which is in good agreement with the previous structure sensitivity studies on NO + CO reactions over Pd. Hence, the present study introduces the surface crystallographic orientation control of foil catalysts as a new development strategy for the unique catalysts in the material gap.
