Preparation of Au nanoparticles by Q switched laser ablation and their application in 4-nitrophenol reduction
Original language description
This work reports the fabrication of Au nanoparticles (NPs) by laser ablation of a gold metal plate immersed in water in the absence of stabilizing agents and their application in the catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) using sodium borohydride (NaBH4) in aqueous media at ambient temperature. UV-Vis, EDS (energy-dispersive X-ray spectroscopy), FESEM (field emission scanning electron microscopy), transmission electron microscopy and inductively coupled plasma-optical emission spectrometry analyses have been applied for the characterization of Au NPs which affirmed that they were successfully synthesized and their size ranged from 5-30 nm. The reduction rate for 4-NP with Au NPs using NaBH(4)was measured via UV-Vis spectroscopy from 250 to 550 nm. The clean and eco-friendly protocol presented here neither produces hazardous wastes nor uses any toxic organic solvents, hazardous reductants and expensive surfactant template or capping agents; Au NPs display high catalytic activity as the reaction was completed within 20 min with 100% conversion.
