Abstract

We herein report an eco-friendly synthesis of platinum nanoparticles (Pt-NPs) using aqueous extracts from water hyacinth plant as efficient reducing and stabilizing agents. The colour change and optical analysis confirmed the formation of Pt-NPs. Transmission electron microscope (TEM) analysis showed that the as-synthesised Pt-NPs are small and spherical in shape with average diameter of 3.74 nm while dynamic light scattering (DLS) analysis showed hydrodynamic size and zeta potential of 73.3 nm and −0.0536 mV respectively. Fourier transform infrared spectroscopy (FTIR) indicated that, the presence of hydroxyl, nitrogen and carbohydrate groups present in the extract are responsible for the reduction and capping of Pt-NPs.
