Abstract
In this report, magnetic iron oxide nanoparticles were synthesized via coprecipitation of Fe2+ and Fe3+ with ammonium hydroxide, and the surface of synthesized nanoparticles was organically functionalized by commercially available amine coupling agent namely, 3-aminopropyl trimethoxysilane (APTS) by using well-known sol–gel method. Further reaction of the synthesized Fe3O4@APTS core-shell magnetite nanoparticles with 2-Chloropyridine via nucleophilic aromatic mechanism in position 2 led to the target molecule Fe3O4@APTS/ 2-Chloropyridine. All prepared materials e.g the magnetite iron oxide, Fe3O4@APTS nanoparticles as well as organically coated Fe3O4@APTS/ 2-Chloropyridine magnetite particles were characterized using Fourier transforms infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). SEM images showed that the Fe3O4@APTS/ 2-Chloropyridine nanoparticles were roughly spherical with average size of 45-55 nm. FTIR indicated the formation of a layer of APTS-Py on the surface of the Fe3O4 magnetite core. Thermogravimetric analysis of the coated APTS-Py on the Fe3O4 surface revealed that 8 % of organic materials coated on iron oxide nanoparticles.
