Catalytic reduction of 4-Nitrophenol to 4-Aminophenol by using Fe2O3-Cu2O-TiO2 nanocomposite

Abstract

In this work, a simple sol-gel method was used to synthesize magnetic Fe2O3-Cu2O-TiO2 nanocomposite by using sol gel method and their application for the catalytic reduction of 4-nitrophenol to 4-aminophenol by using reductant as NaBH4. The synthesized catalyst was characterized by XRD, FT-IR, FE-SEM and EDS have been applied to investigate the structure and morphology of the Fe2O3-Cu2O-TiO2 nanocomposite. The obtained catalyst showed best catalytic ability than pure TiO2. Since the magnetic nanocomposites are readily recovered from the solution phase without centrifugation or filtration. The Fe2O3-Cu2O-TiO2 nanocomposite was synthesized in this work has been exploited as solid phase catalysts for the reduction of 4-nitrophenol in the presence of NaBH4.
