Structural analysis of pure PtCu3 nanoparticles synthesized by modified Polyol process

Abstract

The development of effective multi-functional Pt-based nanoparticles (NPs) with enhanced activity, stability, and reduced cost for advanced applications still remains a challenge. In this study, Pt(acac)2 and Cu(OAc)2 metal precursors were reduced to form Pt-Cu NPs at 140 °C in ethylene glycol and sodium borohydride that is a secondary reducing agent in the modified polyol method. The x-ray diffraction (XRD) and Rietveld refinement analyses confirmed the face-centered cubic PtCu3 structure with the space groups of Fm3 ̅m and a lattice constant of a=b=c=3.6829 Å. The average crystal size was found to be 2.76 nm by Scherrer's formula. Scanning electron microscopy (SEM) images confirm the formation of monodisperse PtCu3 NPs with an average size of 8.04 nm within a narrow range of 5-13 nm. While energy-dispersive x-ray spectroscopy (EDS) analysis confirmed that the composition is formed of 26% Pt and 74% Cu atoms and XRD and EDS analyses were confirmed impurity, by-products, and oxidation free NPs formation.
