Abstract

In this research, Vitis vinifera extract was used as a reducing molecule for the biogenic synthesis of platinum nanoparticles (Vv-Pt NPs). Vv-Pt NPs were extensively characterized by various methods. It has been determined that Pt NPs were spherical shaped and 1.513 ± 0.35 nm in size with TEM analysis. The biological activity of synthesized Pt NPs using Vitis vinifera extract was investigated such as antimicrobial, antioxidant, and DNA cleavage studies. Pt NPs exhibited the highest 2,2-Diphenyl-1-picrylhydrazil (DPPH) radical scavenging activity at 200 mg/L. The synthesized Pt NPs were observed to have significant chemical nuclease activity. Pt NPs were found to have significant antibacterial activity against Gram (−) and Gram (+) bacteria, and the highest antimicrobial activity was observed against E. coli. Then, hydrogen production was investigated due to the catalytic effects of Vv-Pt NPs on the hydrolysis of sodium borohydride (NaBH4). Turnover of frequency (TOF), enthalpy (∆H), entropy (∆S), and activation energy (Ea) values were determined as 1217.20 h−1, 37.70 kJ/mol, −153.66 kJ/mol K, and 40.24 kJ/mol, respectively. It has been observed that synthesized Vv-Pt NPs will be used as nano-drugs and will guide sustainable, renewable, and clean energy studies.
