Abstract

The use of TiO2 nanocomposite modified with Fe3O4 dan Ni dopping for silver ion photoreduction has been successfully carried out. In this study, nanocomposites were fabricated through the sol-gel technique. Structure, optical, and magnetic properties were analyzed using XRD, DRUV-Vis, FTIR, and VSM analysis. The XRD pattern revealed the anatase phase of TiO2 and the iron oxide formed was Fe3O4. UV-Vis spectroscopy showed the formation of absorption in the visible region in the presence of Ni doping. The nanocomposite had magnetic properties of 12.6 emu/g with paramagnetic type. TiO2 nanoparticles presented the percentage reduction of Ag ions with UV and Visible light of 82.65% and 21.43%, respectively, while Fe3O4/ TiO2-Ni with UV and Visible light were 80.93% and 90.72%, respectively. Ni-dopped nanocomposites had shown high photocatalytic activity under both UV and Visible irradiation.
