A green biosynthesis of NiO nanoparticles using aqueous extract of Tamarix serotina and their characterization and application

Nickel oxide nanoparticles were prepared using nickel nitrate as precursor with extract of Tamarix serotina flowers and were characterized using powder X-ray diffraction, infrared and UV spectroscopies, transmission electron microscopy, vibrating sample magnetometry and BET surface area measurements. Also, the nickel oxide nanoparticles were used as a green and recyclable nanocatalyst for the synthesis of quinoline derivatives. The products are obtained in good to high yields (60-90%) from a one-pot reaction of 2-aminobenzophenone and various carbonyl compounds. Copyright (C) 2016 John Wiley & Sons, Ltd.
