Biogenic silver nanoparticles (AgNPs) synthesized by Curcuma longa tube extract and characterized by UV–vis spectroscopy, XRD, TEM and FT- IR, Formation of AgNPs is initially confirmed by UV–vis spectroscopic studies with the specific band at 413 nm. TEM and XRD reports revealed that AgNPs are highly crystalline and rod shaped with average particle size of 30 nm. FT-IR studies indicated the presence of different functional groups on the surface of the AgNPs indicating the stability of AgNPs by capping of biomolecules onto the surface. Further, the bio-synthesized T-SNPs show significant anti-bacterial action on tested pathogenic microorganisms Further catalytic efficiency synthesized AgNPs were evaluated for the reduction/degradation of various organic dyes such as 4methylene blue (MB) and methyl orange (MO) using NaBH4 as reducing agent in the presence of catalytic amount of AgNPs. It was found that degradation was faster. |
