INVESTIGATION OF CATALYTIC BEHAVIOUR OF WO3 DOPED MAGNETIC DENDRIMERS

In this work, WO3 nanoparticle decorated magnetic poliamidoamin (PAMAM) dendrimer nanocomposites were fabricated and used as a catalyser for the reduction of 4-nitrophenol (4-NP). Fe3O4 superparamagnetic iron oxide nanoparticles core. Magnetic produced using hydrothermal synthesis. core was covered with PAMAM dendrimers. The dendrimers in covering process 2nd generation which proposed to protect from losing their characteristics. coated core@shell structure where Fe3O4@G2/WO3 composites obtained. Structural characterization performed microscopic, spectroscopic crystallographic methods SEM, TEM, EDX, XRD used. Vibrating sample magnetometry assessment Caraltytic performance tracked UV-vis spectroscopy. on 4-NP. Reaction rate coefficient kapp calculated found 4x10-3 s-1.
