organic solvents. In this study, NiFe2O4/sawdust nanocomposite was synthesized for removingoil pollutants. The oil-adsorbing nanocomposite could be easily separated from water bymagnet bar. The XRD results show tetragonal phase proving the composite formation. TheFESEM pictures successfully reveal the growth of NiFe2O4 on the sawdust template. The FTIRbands at 422 cm-1 and 615 cm-1correspond to...

in this research an effective and appropriate method has been developed for one-pot synthesis of new n-phenyl fulleroisoxazoline using fe3o4@sio2 nanoparticles as a green magnetically recyclable catalyst. the prepared catalytic samples were characterized by xrd, sem, ft-ir and vsm. the products have been characterized by physical and spectroscopic data such as ir, 1h nmr, 13c nmr, and ms analyses.

a simple, green synthesis of n-alkyl-3-acetyl-2-methylpyrrole derivatives using zno nanoparticles from the three component reaction of aliphatic amines, acetylacetone (as a 1,3-dicarbonyl compound) and α-haloketones under solvent-free condition is described.

nano sulfated titania was tested as solid acid heterogeneous catalyst for the synthesis of 4-(trifluoromethyl) coumarin and coumarin derivatives under solvent-free condition. factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents.  this nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. the prepared sulfated titania s...

In this article, simple, convenient synthesis of 2-aryl-1- arylmethyl-1H-1,3-benzimidazole (1,2-disubstituted benzimidazoles) via condensation of 1,2-phenylenediamine and aromatic aldehydes using SBA-Pr-SO3H as a nanoporous solid acid catalyst in green protocol was reported.

An eco-friendly green mediated synthesis of inorganic nanoparticle is a fast growing research in the limb of nanotechnology. This study reports the synthesis of silver Nanoparticle by using commercially available spice Elettaria cardamomom without the use of toxic chemicals. Visually, the formation of silver Nanoparticle was confirmed by observing the colour changes from pale yellow to dark bro...

Illicium verum Hooker fillius or commonly called star anise is a member of Magnoliaceae. The synthesis of metal nanoparticles is a growing area for research due to its potentiality in the application and development of advanced technologies. In general, nanoparticles are synthesized by using chemical methods which are not eco-friendly. Here, we have used a fast, convenient and environment-frien...
