Summary
Researchers developed a cost-effective and eco-friendly method for synthesizing silver nanoparticles (AgNps) using white sugar and sodium hydroxide under sunlight. This green chemistry approach offers a sustainable alternative for large-scale AgNp production.
Area of Science:
- Nanotechnology
- Green Chemistry
- Materials Science
Background:
- Traditional chemical synthesis of silver nanoparticles (AgNps) often requires high energy, pressure, and technical expertise.
- There is a growing need for sustainable and environmentally friendly methods for AgNp production.
Purpose of the Study:
- To develop a cost-effective, energy-efficient, and simple method for synthesizing AgNps.
- To investigate the use of white sugar and sodium hydroxide (NaOH) in a sunlight-driven synthesis process.
- To characterize the synthesized AgNps and assess the influence of NaOH on the synthesis rate.
Main Methods:
- Synthesis of AgNps using white sugar and NaOH under sunlight.
- Characterization techniques including visual observation, UV-Vis spectrophotometry, FTIR, NTA, and TEM.
- Evaluation of NaOH concentration's effect on AgNp synthesis rate.
Main Results:
- AgNp formation was indicated by a color change from colorless to yellow upon addition of silver nitrate.
- UV-Vis spectroscopy showed a characteristic peak at 409 nm.
- NTA and TEM confirmed the presence of spherical AgNps with diameters ranging from 10-25 nm, stabilized by gluconic acid identified by FTIR.
Conclusions:
- A simple, eco-friendly, and economically sustainable method for AgNp synthesis using white sugar and NaOH has been demonstrated.
- The developed method is suitable for large-scale industrial production of AgNps.
- This approach aligns with green chemistry principles, reducing environmental impact and production costs.
