ABSTRACT. A biosynthesized platinum nanoparticles (PtNPs) using aqueous fruit extracts of S. acuminata is demonstrated in this report. Here, multifunctional plant extracts played a major role in synthesizing PtNPs from its salt. Initially PtNPs was confirmed by UV-visible absorbance spectroscopy, the Face centered cubic structure and amorphous in nature was identified by X-ray diffraction analysis and SAED image from transmission electron microscopy. The average size of nanoparticle is calculated around 3.4 nanometers from TEM and revealed by Dynamic light scattering analysis. Demonstrated the functional groups present in extract and NPs using FT-IR analysis. Furthermore, to know the active polyphenols in the extract, HPLC technique is used. Moreover, These PtNPs showed good catalytic efficiency towards the decolorizing of organic pollutant (4-nitrophenol (4-NP)).
