Novel Synthesis, Characterization and Antimicrobial Activities of Silver Nanoparticles in Room- Temperature Ionic Liquids

چکیده
Stable silver nanoparticles were successfully synthesized by chemical reduction of silver nitrate in ionic liquids 1Ethyl-3-methylimidazolium tetrafluoroborate [Emim] BF4 and 1Ethyl-3-methylimidazolium hexafluorophosphate [Emim] PF6 at room temperature. The characterization of the silver nanoparticles such as their size and shape was performed by X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM) techniques which indicated a size range of 50 to 55 nm. The antimicrobial activity of silver nanoparticles for three gram negative bacteria and three gram positive bacteria were investigated. It appeared that [Emim] PF6 and its Ag nanoparticles are the most effective products against the tested bacterial stains compared with [Emim] BF4 and its Ag nanoparticles.

For the synthesis of Mequinol (4-methoxy phenol), two acidic ionic liquids based on imidazolium cation (BMSIL and IMSIL) synthesized and characterized by FT-IR, 1H NMR, and CHNS analyses. Tan, the Baeyer–Villiger oxidation of para-anisaldehyde was studied with these ionic liquids, as the catalysts. The results showed that the BMSIL with more Brønsted acidic functions had higher c...
