Abstract

Background: Silver nanoparticles possess distinctive characteristics, including chemical stability, high thermal and electrical conductivity, and linear optical properties, making them unique and fascinating. The rise of green synthesis methods for silver nanoparticles is garnering significant interest among researchers, surpassing traditional chemical and physical approaches due to the environmentally friendly, cost-effective, and convenient nature of synthesis. This approach stands as a viable alternative across various sectors, encompassing research, industry, and environmental safety initiatives. Method: Parmotrema permutatum was utilized in the synthesis of silver nanoparticles, followed by their characterization using ultraviolet-visible spectroscopy, Fourier-transformed infrared spectroscopy, X-ray diffraction, energy dispersive X-ray analysis, and scanning electron microscopy. These nanoparticles are subsequiently employed for detecting methylene blue, formaldehyde, and hazardous mercury metal ions as well as photocatalytically degrading methylene blue. objective: Green Synthesis of Silver Nanoparticle Using Parmotrema parmutatum Extract and Its Application in Colorimetric Sensing Results: The silver nanoparticle synthesized was confirmed by a color change and the maximum peak of the SPR band was at 420 nm in the UV spectrum. The crystal has face-centered cubic (FCC) structure with an average size of 12.78 nm. The lichen extract contains polyphenolic groups which act as capping agents. synthesized silver nanoparticles were used to detect formaldehyde and hazardous Hg2+ ions separately. A color change was observed. The detection limit of Hg2+ was 600 μL. Likewise, silver nanoparticles were used to degrade methylene blue. The blue color of methylene blue disappeared. The efficiency of silver nanoparticles was found to be 72% in 4 hours and 87.82% in 24 hours. Conclusion: Parmotrema permutatum has the potential to reduce Ag2+ to Ago and acts as a capping and stabilizing agent, it can be used to biosynthesize silver nanoparticles and can detect formaldehyde, and Hg2+ ions, in addition, it also degrades methylene blue photolytically.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
