Nanoscale Ag–Pd and Cu–Pd alloys

Abstract

Nanoparticles of Ag–Pd and Cu–Pd alloys with diameters in the 5–40 nm range have been prepared over the entire range of compositions, by employing the heterogeneous reaction of dry methanol or ethanol with intimate mixtures of AgNO₃+ PdO_x and CuO_x+ PdO_x, respectively. The nanoscale alloys have been characterized by energy-dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM) and X-ray diffraction (XRD). All the alloy particles possess the fcc structure and can be obtained in bulk quantities.
