Description

This study describes the rapid microwave assisted synthesis of “naked” silver nanoparticles upon the reduction of silver oxide (Ag2O) by molecular hydrogen. These nanoparticles were also compared with the well-established reduction of silver nitrate by trisodium citrate which gave similar UV-Vis absorption spectral, the latter being suspended by organic molecules. By this method, it was found that silver nanoparticles can be synthesized in seconds or a few minutes while the reported “naked” silver nanoparticles took two – eight hours at relatively elevated pressure of 1.5 – 1.7 atmospheres. Further, their application as antibacterial activities will be explored.
