Green Synthesis of Antioxidant Silver and Platinum Nanoparticles Using Ginger and Turmeric Extracts and Investigation of Their Catalytic Activity

Antioxidant silver nanoparticles (AgNPs) and platinum nanoparticles (PtNPs) were synthesized using from ginger and turmeric extracts by green method in this work. Thus synthesized these nanoparticles were characterized by UV-VIS spectroscopy, SEM-EDX and FTIR. The UV visible spectra of the AgNPs revealed a characteristic surface plasmon resonance peak at 420-425 nm and the UV visible spectra of the PtNPs revealed a characteristic surface plasmon resonance peak at 234-240 nm. The synthesized AgNPs and PtNPs were acted as a catalyst to degradation of dyes (rhodamine B, methyl orange and methylene blue) with sodium borohydride (NaBH4). Green synthesized antioxidant silver nanoparticles were effectively degrading the dyes nearly 4-10 min. and green synthesized antioxidant platinum nanoparticles were effectively degrading the dyes nearly 15-24 min. of exposure time.
