Biogenic Synthesis of Silver Nanoparticles using Pomegranate Peel Polyphenols and Its Catalytic Action in Reduction of Acid Red 6

摘要

A biogenic synthesis of silver nanoparticles (AgNPs) was achieved using pomegranate peel polyphenols in this article. The formation of AgNPs was confirmed by UV-vis spectrum and TEM image. The biogenic AgNPs showed Surface Plasmon Resonance (SPR) peak at 433nm as shown from the UV-vis absorption spectrum. The average diameter of AgNPs was around 26nm, which was testified by the particle size distribution analysis. The biogenic AgNPs were utilized for the catalytic reduction of Acid Red 6, and the green synthesized AgNPs showed high catalytic activity on Acid Red 6 reduction in the presence of NaBH_4. The present study has brought to a novel method for the reduction of hazardous dyes in the liquid phase.
