The present article reports an environmentally benign method for synthesizing silver nanoparticles using the fruit extract of Viburnum opulus L. as a source of bioactive compounds, which can act as reducing agents of the silver ions and also as stabilizing agents of the obtained nanoparticles. The catalytic ability of the synthesized silver nanoparticles (AgNPs) to remove toxic organic dyes was also evaluated. The biosynthesis of silver nanoparticles was firstly confirmed by UV-Vis spectral analysis, which revealed the presence of the characteristic absorption peak at 415 nm corresponding to the surface plasmon vibration of colloidal silver. Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) studies were conducted to confirm the presence of bioactive phytocompounds, especially phenolics, as capping and stabilizing agents of the AgNPs. The size, morphology and crystalline nature of the synthesized AgNPs were investigated by transmission electron microscopy and X-ray diffraction techniques revealing that the obtained nanoparticles were spherical shaped, with an average diameter of 16 nm, monodispersed, face centered cubic nanoparticles. Further, the catalytic ability in the degradation of tartrazine, carmoisine and brilliant blue FCF dyes by NaBH4 was evaluated. The results demonstrated an efficient activity against all the investigated dyes being an outstanding catalyst for the degradation of brilliant blue FCF. This eco-friendly synthetic approach can generate new tools useful in environmental pollution control. View Full-Text
