Abstract

   Silver nanoparticles (Ag NPs) were synthesized at room temperature using Hibiscus sabdariffa L as a green reducing agent. Characterization techniques including XRD, Raman spectroscopy, EDX, FE-SEM, FTIR, UV-Vis-NIR spectroscopy, and fluorescence spectrum were employed to analyze their structural, optical, and chemical properties. The average crystallite size of the nanoparticles was determined to be 48.64 nm using Scherer's equation. The FTIR spectra covered a range of 400-4000 cm-1, while UV-Vis-NIR spectroscopy revealed absorption in a wavelength range of ( 200-1100) nm. The fluorescence spectrum exhibited a peak wavelength of 450 nm. These silver nanoparticles hold immense potential for applications in sensors, electronics, medical devices, and more .The photo catalytic tests for samples prepared using methylene blue as a colorant were successful using silver nanoparticles , while the percentage of color degradation varied between the various samples , the percentage of degradation for all enamels after two hours of exposure to sunlight exceeded 90% which confirms the success of the photo catalytic process using silver Nano crystalline.
