Green synthesis of TiO2 nanoparticles as an efficient heterogeneous catalyst with high reusability for synthesis of 1,2-dihydroquinoline derivatives
Nano materials find wide applications due to their behavior at nano scale. TiO2 nanoparticles (TiO2 NPs) was synthesized using Neem leaf extract. This is simple, rapid, eco-friendly, cheaper and green tools for TiO2 NPs synthesis using agricultural waste at lower applied temperature. Characterization of the extracted TiO2 NPs was confirmed by XRD, SEM, EDAX, TEM, HR-TEM, SAED, and FT-IR, respectively. ... Read more

CuFe2O4 nanoparticles: an efficient heterogeneous magnetically separable catalyst for synthesis of some novel propynyl-1H-imidazoles derivatives
The non-toxic magnetic CuFe2O4 nanoparticles have been synthesized, characterized, and used as an efficient catalyst for synthesis of new derivatives for 1,2,4,5-tetrasubstituted imidazoles in excellent yields. The synthesized compounds work-up easy and purification of products are performed without chromatographic methods. The catalyst can be recovered for the subsequent reactions and reused without any appreciable loss. Read more

A robust synthesis and characterization of superparamagnetic CoFe2O4 nanoparticles as an efficient and reusable catalyst for green synthesis of some heterocyclic rings
A robust synthesis for magnetic CoFe2O4 nanoparticles via a hydrothermal technique was investigated. The prepared magnetic nanoparticles were characterized using powder X‐ray diffraction, scanning, transmission and high‐resolution transmission electron microscopies, energy‐dispersive X‐ray and infrared spectroscopies, thermogravimetric analysis and vibrating sample magnetometry. Based on the obtained data, the prepared powder was composed of ultrafine particles in nanometer size range with highly ... Read more
