Silica coated magnetite nanoparticles were covalent grafted with 3-aminopropyl trimethoxysilane to give APTSCMNPs. Reaction of the resulted nanomaterial with 4-formyl benzo-12-crown-4 ether afforded FB12C4/APTSMNPs nanocomposite material in which the crown ether moiety was attached through propyl chain spacer. Characterization of the prepared nanocomposite was performed wit...
V2O5/SiO2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethylorthosilicate in refluxing MeOH, followed by calcination at 700 °C for 2 hours. The resultant nanoparticles was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), TGA and FTIR techniques. Rapid and efficient ar...
