Synthesis of Posnjakite Nanoparticles in the Presence of a New Capping Agent

Abstract

Posnjakite nanoparticles, Cu4SO4(OH)6 · H2O, were synthesized by utilizing a new thio-Schiff base ligand as new capping agent via a microwave approach. The effects of molar ratio, surfactants, heating time and microwave power on morphology of the product were investigated. The as-synthesized posnjakite nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy and energy dispersive X-ray analysis (EDAX). The effects of different parameters such as the molar ratio, surfactants, microwave power and irradiation time on the morphology of the products were investigated. Moreover, adsorption of methylene orange dye on posnjakite nanoparticles was considered and the uptake percent was determined to be >65% in 200 min.
