Abstract
Argon-saturated aqueous solutions of NaAuCl4 and PdCl2 or K2PtCl4 were reduced simultaneously by ultrasound irradiation to prepare noble metal alloy nanoparticles. Droplets recovered from colloidal dispersions were placed on carbon-supported copper grids, and dried in a vacuum. They were examined by TEM, HRTEM, and nano-area energy dispersion X-ray spectroscopy (EDX). The Au-Pd nanoparticles exhibited monodispersive distribution (8 nm), and consisted of a gold core and a palladium shell. Au-Pt alloys nanoparticles could not be produced from NaAuCl4 and K2PtCl4 aqueous solutions either by simultaneous or successive reduction.
