Synthesis of Silica Coated Magnetic Nanoparticles
In this research controlled coating of magnetite (Fe3O4) nanoparticles with SiO2 was investigated. The Fe3O4 nanoparticles were synthesized via chemical co-precipitation and then coated by silica according to Stober method. Effects of tetra ethyl ortho silicate (TEOS) concentration and ethanol to TEOS on the coating thickness were inves...

15 صفحه اولAlkanedisulfamic acid functionalized silica-coated magnetic nanoparticles as a reusable efficient nanocatalyst for synthesis of gem-dihydroperoxides and 1,2,4,5-tetraoxanes
Alkanedisulfamic acid functionalized silica-coated magnetic nanoparticles (ADSA-MNPs) were used as effective, low-cost and reusable solid heterogeneous nanomagnetic catalysts for conversion of aldehydes and ketones to corresponding gem-dihydroperoxides and 1,2,4,5-tetraoxanes using aqueous hydrogen peroxide (30% w/w in H2O) at room temperature. These compounds are important ...
