Platinum nanoparticles using wood nanomaterials: eco-friendly synthesis, shape control and catalytic activity for p-nitrophenol reduction

Abstract

We report a one-step and environment-friendly synthesis of platinum nanoparticles with controlled shapes and sizes using wood nanomaterials in aqueous phase without employing any other reductants, capping or dispersing agents. This green process affords an easy route to the production of shape-selective metal nanoparticles. The obtained spherical and cubic Pt nanoparticles and spherical Pt nanoclusters exhibit high activities in the catalytic reduction of p-nitrophenol as a model reaction.
