Synthesis and characterisation of hollow MPt (M=Co, Fe) alloys nanostructures trended for fuel cell application

Abstract

This paper describes a facile synthetic method for the preparation of hollow CoPt and FePt alloy nanoparticles with controllable size. Here, the particle size (perimeter size) could be tuned from 17 to 70 nm by changing the length and concentration of PVP polymer. The obtained nanoparticles have been characterised by Transmission electron microscopy (TEM), X-ray diffraction (XRD) and Energy dispersive X-ray spectroscopy (EDS).
