dc.description.abstractMagnetic nanoparticles (MNPs) and nanocomposites can be used in different applications including catalysis reactions and applications. Magnetic nanocomposites can be reused and magnetically filtrated after catalysis reaction. For this purpose, Fe3O4 MNPs were produced using the co-precipitation technique. Fe3O4 MNPs were coated with SiO2 shell, APTES and G2 PAMAM dendrimers and lastly doped with Au and Ag nanoparticles (Fe3O4@G2/Au/Ag) which has been examined for the catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) by NaBH4 as a model reaction. Physical structures of the nanocomposites were characterized using SEM and TEM which illustrate that nanoparticles were in composite form. Chemical composition of nanostructures was confirmed using EDX and FTIR. Magnetic characteristics were checked using VSM. Dendrimerization and Au and Ag nanoparticle doping on catalytic and magnetic properties were deeply assessed. PAMAM dendrimer coating on Fe3O4 nanoparticles results in a slightly decreased magnetic saturation value and in the reaction rate of 4-NP reduction. Au and Ag embedding in PAMAM dendrimers slightly increases the reaction rate while reducing the overall magnetic saturation values of nanocomposites. [GRAPHICS] .en_US
