Abstract
In this study, Pd nanoparticle-modified magnetic Sm2O3-ZrO2 material (Pd-Fe3O4-Sm2O3-ZrO2) as multifunctional catalyst was fabricated and used for catalytic reduction of 2-nitrophenol compound, degradation of methylene blue and rhodamine B dyes, which are toxic pollutants. The magnetic material was used for the first time as a catalyst for the reduction and degradation studies. Pd nanoparticle-modified magnetic Sm2O3-ZrO2 catalyst was prepared using the deposition-precipitation methods and were characterized by X-ray diffraction, scanning electron microscopy, atomic absorption spectrometry, Raman spectroscopy and BET surface analyzer. The Pd nanoparticle-modified magnetic Sm2O3-ZrO2 material can lead to high catalytic activity for the reduction of 2-nitrophenol and degradation of rhodamine B and methylene blue with > 95% conversion within similar to 2 and 80 s even when the content of Pd in it is as low as 5.8 wt%.
