We synthesized different Fe/TiO2 catalysts and studied the influence of Fe on the structure and performance of Fe/TiO2 as a photocatalyst to remove gaseous NO in air under visible light. The electron paramagnetic resonance results revealed that Fe ions substituted the Ti ions of TiO2 prepared by coprecipitation and homogeneous precipitation method. More Fe ions were incorporated into the crysta...

First, crystalline NiFe2O4 powder was synthesized on a nanoscale dimension by a simple one-step coprecipitationchemical route, and then used to produce activated carbon/NiFe2O4 nanocomposite. Thestructure and morphology of the as-prepared composite was characterized by X-ray diffraction (XRD)pattern, transmission electron microscope (TEM) and Fourier transform infrared (FT-IR)...

The reverse co-precipitation method was used for synthesis of the pure phase multiferroic BiFeO3 (BFO) nanoparticles. Influence of different pH values on the microstructure and magnetic properties of the BFO nanopowders was investigated. Thermogravimetric-differential thermal analysis (TG-DTA) technique indicated that the optimal temperature for calcination is 550°C. The phase formation and the...

A co-precipitation method was used for synthesis of pure MgTiO3 ceramic powder with Mg(NO3)2.6H2O, TiCl4 or C12H28O4Ti and NaOH as raw materials. In this method, solutions of 1 M, Mg (NO3)2 6H2O and 2 M, NaOH were prepared. A stoichiometric amount of Ti precursors from TiCl4 or C12H28O4Ti was weighted. Solutions of Mg (NO3)2. 6H2O and Ti precursor were added dropwise to NaOH solution unde...

The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...
