[ 1 ] - Hybrid Organometallic-Inorganic Nanomaterial: Acetyl Ferrocene Schiff base Immobilized on Silica Coated Magnetite Nanoparticles

In this work, a new hybrid organometallic-inorganic hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the surface of magnetite nanoparticles. Covalent grafting of silica coated magnetite nanoparticles (SCMNPs) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (AmpSCMNPs). Then, Schiff base condensation of AmpSCMNPs with acet...

[ 2 ] - Immobilization of Phosphomolybdate Anions on the Surface of Magnetite Nanoparticles Modified with Quaternary Phosphonium Cations

A new hybrid nanomaterial was developed by immobilization of phosphomolybdate anions on the surface of modified magnetite nanoparticles with quaternary phosphonium cations. Silica coated magnetic nanoparticles supported phosphonium cations, Ph3P+-SCMNPs, were prepared by covalent attachment of chloropropylsilyl groups on the surface of silica coated magnetite nanoparticles...
