Abstract

This study describes the environmentally friendly synthesis of zinc oxide nanoparticles (ZnO-NPs) using cinnamon extract, bay leaf extract, and chemical techniques. Due to its cost-effectiveness and avoidance of harmful ingredients, the green synthesis strategy for producing nanoparticles has significant advantages over physical and chemical procedures. The XRD data demonstrated the production of a hexagonal wurtzite structure, while the SEM investigations demonstrated a spherical shape and average size (21.49, 25.26) nm for ZnO NPs synthesized by cinnamon extract, bay leaf extract, and chemical techniques, respectively. The synthesized ZnO NPs demonstrate noteworthy photocatalytic efficacy in the breakdown of methylene blue dye under direct sunlight exposure. Therefore, this research signifies a significant advancement in the progress of a sustainable photocatalyst to eliminate harmful dyes from water.
