Synthesis and Use in Catalysis of Hematite Nanoparticles Obtained from a Polymer Supported Fe(III) Complex

Abstract Weakly magnetic hematite (α‐Fe 2 O 3 ) nanoparticles were synthesized by heating an amorphous polymer supported iron(III) complex ( Fe_POL at 400 °C for 4 h in air. The growth of (NPs) was studied PXRD, the from 150 to 25 intervals, revealing that, all temperatures, only crystalline phase detected is hematite. Conversely, annealing under nitrogen, yielded a material containing wüstite (FeO) as phase, onto pyrolised acrylamidic polymer. materials characterized TXRF, SEM‐EDS, XPS, Raman and FTIR spectroscopy well analysis. Differently natural micrometric hematite, synthesised nano‐hematite turned out be efficient recyclable catalyst hydrogenation nitroarenes corresponding anilines.
