Plant-mediated synthesis of Au–Pd alloy nanoparticles supported on MnO2 nanostructures and their application toward oxidation of 5-(hydroxymethyl)furfural

Abstract

A facile and eco-friendly preparation method for Au–Pd bimetallic nanoparticles (NPs) supported on MnO₂ with two different morphologies was adopted with Cacumen platycladi leaf extract. The biosynthetic NPs, MnO₂ nano-structures and the resulting catalysts were characterized. The effects of Au–Pd ratio, catalyst size and reaction conditions were examined.
