In this study, zinc oxide nanoparticles (ZnONPs) were synthesized using pistachio skin extract in the role of a green and eco-friendly approach. The synthesized ZnONPs were characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and UV-Visible spectroscopy. The results confirmed the successful synthesis of ZnONPs with a crystalline structure with spherical morphology. The UV-Visible spectroscopy analysis showed a band gap energy of 3.17 eV for the ZnONPs. Furthermore, the photocatalytic activity of the synthesized ZnONPs was evaluated for the degradation of some organic dyes, including methylene blue, acid blue, rhodamine B, and eosin Y. The results showed that ZnONPs show effective photocatalytic degradation of the dyes under UV radiation as well as visible radiation with good to excellent efficiency. Overall, the pistachio skin extract-mediated ZnONPs showed promising photocatalytic activity for the degradation of organic dyes, highlighting their potential application in wastewater treatment and environmental remediation. This green synthesis approach offers a sustainable and cost-effective method for producing of ZnONPs with enhanced photocatalytic properties.
