Cyclea peltata Leaf Mediated Green Synthesized Bimetallic Nanoparticles Exhibits Methyl Green Dye Degradation Capability

摘要

Nowadays, biological materials are explored widely for green synthesis of nanoparticles because of its ease in scaling up when compared with conventional approaches. In this paper, we report the biosynthesis of bimetallic nanoparticles (FeCuNPs) from their precursors FeSO4 and CuSO4, using Cyclea peltata leaf extract. Biosynthesized nanoparticles were characterized by UV-visible spectroscopy, particle size analyser, FESEM, EDAX, XRD and FTIR. UV-visible spectroscopic investigation confirmed the production of bimetallic core shell nanoparticles at 250 nm, where the colour change in the solution indicated the formation of nanoparticles. The synthesized FeCuNPs were tested for their methyl green dye degradation and degradation kinetics. Results indicated that bimetallic nanoparticles could effectively degrade methyl green dye up to 82% within 105 min, which followed pseudo second order kinetics with R-2 of 0.9862. Hence time-dependent reduction in methyl green absorption maxima, obtained from UV-Spectrophotometric analysis and LCMS spectra of degraded dye, confirmed that the green synthesized bimetallic nanoparticles from the leaf extract of Cyclea peltata has the potential of dye degradation.
