Generation six hydroxyl terminated PAMAM dendrimer was used as template for the synthesis of several palladium-gold random alloy nanoparticles. The synthesis process was monitored using UV-spectroscopy. The microscopy image of the alloy nanoparticles was captured by transmission electron microscopy and their average size was compared to the theoretical value. Catalytic oxidation of morin by hydrogen peroxide was performed to investigate the activity of the alloy nanoparticles. The Langmuir-Hinshelwood approach was used to conduct a full kinetic evaluation of the catalytic process. The catalytic activity exhibited by the alloy nanoparticles demonstrates a proportional increase with the relative palladium amount. The encapsulated alloy and mono metal nanoparticles remained narrowly dispersed after the reaction. (C) 2016 Elsevier B.V. All rights reserved.
