Synthesis and structural analysis of gold-palladium alloy nanoparticles using co-sputtering of independent sources

Abstract

In this work, a Mantis Nanosys 500 equipment was modified by the addition of a second magnetron in a different chamber to obtain gold/palladium bimetallic alloy nanoparticles at room temperature using two independent targets by Inert Gas Condensation (IGC) technique. The nanoparticles were characterized by mass spectroscopy, transmission electron microscopy (TEM) and chemical composition TEM-EDS. A structural analysis was carried out, and the results indicate that the nanoparticles are formed by an evenly distributed alloy of gold/palladium.
