Abstract

Nano-sized iron oxide particles such as maghemite γ-Fe2O3, hematite α-Fe2O3 and magnetite Fe3O4 are well known for their multiple applications such as; medicine, catalysis, sensors, memory devices and electronics. In photocatalytic properties, these particles play important role as holder for photocatalytic compounds, such as co-dopped TiO2. In order to maintain high surface area of such photocatalytic compounds and to get easy and economic process of restoring photocatalysts from the cleaning system utilizing their magnetic behaviour, these particles are used for also preparing core-shell catalysts. In present study, the nanosized iron oxide particles are synthetized by precipitation of Mohric salt (NH4)2Fe(SO4)2·6H2O with sodium hydroxide solution and later in the process they are coated with nanosized TiO2. XRD, SEM and pH measurements are used in this study.
