Catalytic reduction of 4-Nitrophenol by using Fe3+and Ag+ Co-doped TiO2 nanoparticles

P. Babji | I. Nageswara Rao

Abstract: In this work, a simple sol-gel method was used to prepare magnetic Fe3+ and Ag+ co-doped TiO2 nanoparticles and their application for the catalytic reduction of 4-nitrophenol to 4-aminophenol by using reductant as NaBH4. The prepared catalyst was characterized by XRD, FT-IR, Uv-DRS, FE-SEM, EDS and VSM have been applied to investigate the structure, morphology and magnetism of the nanoparticles. The obtained catalyst showed an excellent magnetism and the best catalytic ability than pure TiO2. The magnetic nanocatalyst should be extended to various potential applications, such as photo-degradation, separation and purification processes. Since the magnetic particles are readily recovered from the solution phase without centrifugation or filtration. The Fe3+ and Ag+ co-doped TiO2 nanoparticles prepared in this work has been exploited as solid phase catalysts for the reduction of 4-nitrophenol in the presence of NaBH4.
