Synthesis of Fe <sub>2</sub> O <sub>3</sub> Nanoparticles and their Catalytic Activity for the Reduction of Halonitroarenes under Sustainable Conditions
نویسندگان
چکیده
Fe2O3 nanoparticles (NPs) with mean size of 50 nm ca. are synthesized starting from a porous organic polymer containing β-ketoesterate Fe(III) sites (Fe-POP), which is annealed at 400 °C under air for 30 min. During calcination, the material partially decomposes, and iron(III) oxide NPs onto an residue could be observed after annealing. The obtained characterized by SEM-EDS, IR, magnetic analyses they employed as active catalysts in reduction p-bromonitrobenzene into p-bromoaniline, using hydrazine hydrate ethanol.

Preparation of Gd2O3 nanoparticles from a new precursor and their catalytic activity for electrochemical reduction of CO2 to CO
The mononuclear Gd(III) complex, [Gd(L)3(H2O)5] (where L is alizarin yellow R (NaC13H8N3O5)), has been prepared in H2O under reflux condition. The Gd(III) complex has been characterized by elemental analysis and spectroscopic methods (UV–Vis and FT–IR). The Gd2O3 nanoparticles were prepared by the calcination of the Gd(III) complex in air at different temperatures up to 600 °C for 2 h. The calc...
متن کاملSynthesis of CuO Nanoparticles and Study on their Catalytic Properties
In this research, CuO spherical-like nanoparticles were synthesized using the planetary ball mill method. The structure, particle size and morphology of the resulting CuO nanoparticles were characterized by XRD (X-ray diffraction), SEM (scanning electron microscopy) and SAXS (small-angle X-ray scattering) methods. The results of this investigation showed ...
