Area of Science:

• Materials Science
• Nanotechnology
• Green Chemistry

Background:

• Zinc oxide nanoparticles (ZnONPs) have diverse applications in optics, electronics, food packaging, and biomedical fields.
• Traditional synthesis methods often involve harsh chemicals and conditions.
• Developing eco-friendly and sustainable synthesis routes for ZnONPs is crucial.

Purpose of the Study:

• To investigate the green synthesis of ZnONPs using Crinum asiaticum leaf extract.
• To characterize the synthesized ZnONPs and analyze the influence of plant extract volume on their properties.
• To establish Crinum asiaticum as a viable source for sustainable ZnONP production.

Main Methods:

• Green synthesis of ZnONPs using Crinum asiaticum leaf extract.
• Characterization via UV-Vis spectroscopy, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), atomic force microscopy (AFM), and particle size analysis.
• Systematic variation of Crinum asiaticum leaf extract volume during synthesis.

Main Results:

• Synthesized ZnONPs showed a characteristic UV-Vis absorption peak at 399 nm.
• XRD confirmed a hexagonal wurtzite crystal structure for the ZnONPs.
• Increased plant extract volume improved ZnONP crystallinity, stability, size, and structural order, with FTIR revealing functional group interactions.

Conclusions:

• Crinum asiaticum leaf extract is an effective, eco-friendly, and sustainable precursor for ZnONP synthesis.
• The volume of plant extract significantly influences the physicochemical properties of the synthesized ZnONPs.
• This green synthesis approach offers a pathway for tailoring ZnONP characteristics for specific applications.
