Cobalt Ferrite Nanoparticles: Preparation,characterization and salinized with 3-aminopropyl triethoxysilane

摘要

Coprecipitation method was used to prepare pure and doped CoFe204 nanoparticles.Ferric and cobalt salts were used as precursors while Sodium Dodecylbenzene Sulfonate was used as surfactant.Surface functionalization of cobalt ferrite nanoparticles(NPs)is a kind of functional materials,which have been widely used in the biotechnology and catalysis.The fabricated cobalt ferrite nanoparticles were functionalized with amino propyl triethoxy silane(APTES)by silanization reaction and both non-coated and organosilane-coated magnetite characterized by energy-dispersive X-ray spectroscopy(EDX),X-ray diffractometry,Fourier transformed infrared spectroscopy(FTIR),atomic force microscopy(AFM)and filed emission scanning electron microscope(FESEM).Basic groups of amino anchored on the external surface of the coated magnetite were observed.The nanoparticles above have surface with free-NH2 groups which can transport ionic interface with carboxylic groups and act as a transporter of biological molecules,drugs,and metals.
