Preyssler Heteropolyacid: A Green Co-reducing Agent In The Bio-synthesis Of Ag Nanoparticles In The Presence Of Chaetomorpha Linum Seaweed

The capability of the sodium 30-tungstopentaphosphate, as a green and co-reducing polyoxometalate was investigated in the bio-syntheses of silver nanoparticles in the presence of chaetomorpha linum seaweed. The synthesized silver nanoparticles were characterized, using UV-Visible absorption spectroscopy, transmission electron microscopy (TEM), and X-ray diffraction analysis (XRD). Interestingly, we found no report concerning the synthesis of Ag nanoparticles using Chaetomorpha linum in combination with sodium 30-tungstopentaphosphate as co-reductant. The antibacterial activities of the biosynthesized silver nanoparticles were investigated in concretes and the results showed that these nanoparticles displayed a good activity against bacterial cultures.
