In situ encapsulation of Pd crystals inside foam-like carbon films continuously filled with α-Fe: investigating the nucleation of FePd3 alloys

Abstract

A key challenge in the fabrication and encapsulation of FePd alloys inside carbon materials is the achievement of continuous Fe_xPd_x filling rates. We propose an advanced approach which allows the encapsulation of Pd crystals into foam-like carbon films continuously filled with α-Fe and the subsequent nucleation of the FePd₃ alloys. The alloying-mechanism is also investigated.
