Preparation and Characterization of Nanospherical α-Fe2O3 Supported on the Surface of an Inorganic Silica Using Solid-State Dispersion (SSD)

The effective supportation of nano particles specialty metal oxide on the surface of different catalyst supports including organic, inorganic or organic-inorganic catalyst supports is a suitable method for improvement of nano particle properties and increasing of catalysts yield. In the paper, spherical α-Fe2O3 nanoparticles were supported on the surface of inorganic silica as a catalyst support, using solid-state dispersion (SSD) method. All products were characterized by using XRF, FTIR, SEM, XRD and BET surface area. The results indicated that the supported nanocatalyst (α-Fe2O3 /Silica) successfully was prepared. By using XRD analysis and
Warren-Averbach method average size of spherical α-Fe2O3 NPs supported by SSD method were measured 27.50 nm. The nanocatalyst presented in this study can be applied in the different areas such as catalytic and photocatalytic reactions.
