A facile and reliable route to prepare of lead sulfate nanostructures in the presence of a new sulfur source

摘要

With the presence of [(2-suphanylphenyl)imino]-methylphenol (thio Schiff-base), which was used as a sulf-uring agent, lead sulfate (PbSO_4) nanocrystals with different morphologies were successfully synthesized via a simple microwave reaction. The obtained products were analyzed by X-ray diffraction scanning electron microscopy and ultraviolet-visible (UV-Vis) spectroscopy. The results showed that microwave temperature and time, concentration of precursors played key roles in controlling the morphologies of the products. Also, the band gap of HgS nanoparticles was calculated by UV-Vis spectrum.
