High-Potential of the Super-Paramagnetic of Fe3O4 with Coating by Silica-Thiol and Immobilization by Palladium on Oxidation of Benzyl Alcohols in Aerobic System
Author(s): Mansour Binandeh* and Sadegh Rostamnia
In this project, the effect of magnetic nanoparticles on the exchange and conversion of the functional group (-OH) of benzyl alcohol to the functional group (-COH) in aldehyde was investigated. For this purpose, magnetic nanoparticles (MNPs) were synthesized by chemical co-precipitation method, whose core/shell structure was confirmed by tools such as XRD, FT-IR and VSM analyzes. Next, magnetic nanoparticles (Fe3O4), for enhanced efficiency, are coated with silica and then with 3-mercapropropyl tritoxy silane (MPTES) and imidazole (to improve coating) and finally with some Pd (for immunization) over several steps in Distilled water was modified and synthesized at temperatures of 25°C-100°C. The product was named magnetic nanoparticles [Fe3O4@SiO2/SH/Pd]. The purpose of this work was to use this comple.. Read More»
