Green platinum nanoparticles were synthesized using a reductant derived from Atriplex halimus leaves, exhibiting stability and excellent catalytic, antibacterial, and antioxidant properties.
Herein, green platinum nanoparticles (PtNPs) were synthesized using an aqueous extract of Atriplex halimus leaves as a reductant. Atriplex platinum nanoparticles (At-PtNPs) were stable for up to three months. At-PtNPs were characterized by several techniques including UV-Visible spectroscopy, Fourier Transform Infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), Energy Dispersive X-ray spectroscopy (EDX), EDX elemental mapping, High-resolution Transmission electron microscope (HRTEM), Selected Area Electron Diffraction (SAED), and X-ray Photoelectron Spectroscopy (XPS) and Zeta measurements. At-PtNPs were black-colored and mainly spherical with a plasmon peak at 295 nm with ultra-small particle size (1-3 nm) and high surface charge (-25.4 mV). At-PtNPs were verified as a superb catalyst as they were able to catalytically degrade MB dye. At-PtNPs exhibited a high antibacterial efficiency against gram-negative bacteria. At-PtNPs were proved as a highly efficient antioxidant agent. Thus, the attained results offer a promising route of the green synthesis of PtNPs using the aqueous extract of Atriplex halimus.
