Synthesis and Catalytic Performance of Al-Pillared Clays Supported Fe₃O₄ Nanoparticles

Abstract:

Al-pillared bentonite supported Fe₃O₄ nanoparticles were prepared by co-precipitation and characterized with X-ray diffraction (XRD), specific surface area (BET) and scanning electron microscopy (SEM). The supported Fe₃O₄ nanoparticles exist on the surface of clays, with better dispersing and no obvious aggregation than the ones without bentonite support. Batch tests were carried out to investigate the catalytic oxidation Orange II by the obtained heterogeneous catalysts. The effect of pH, temperature and initial H₂O₂ concentration on degradation was discussed, and the regeneration ability of catalyst was also studied.
