•Pt-NPs are biofabricated using agro-industrial waste Punica granatum's peel.•Pt-NPs are characterized by UV, DLS, TEM, XRD, EDX and FTIR.•Spherical, crystalline Pt-NPs are synthesized within size range of 16–23 nm.•3-Nitrophenol is reduced by NaBH4 using colloidal Pt-NPs as catalyst.
The present study showed biofabrication of platinum nanoparticles (Pt-NPs) using agro-industrial waste Punica granatum's peel extract. Appearance of the broad spectrum from visible to the ultraviolet region, confirmed the biofabrication of Pt-NPs. Pt-NPs were spherical, within size range of 16–23 nm. XRD suggested the fabrication of crystalline Pt-NPs with (111) plane in predominant orientation. The negative ζ potential value of colloidal Pt-NPs revealed high stability. FTIR confirmed the role of hydroxyl and carbonyl groups of polyphenolic compounds of peel extract for biofabrication. The reduction of anthropogenic pollutant, 3-nitrophenol, by NaBH4 using colloidal Pt-NPs established it as an efficient “green catalyst.”
