Abstract

The xZnFe2O4–(1−x)SmFeO3 (x = 0.1, 0.2 and 0.3) nanocomposite were synthesised through the thermal decomposition technique and calcinated at 873 K. The obtained nanocomposite was examined using XRD, SEM with EDS, UV-DRS, and TEM with SAED. XRD exhibits a spinel-perovskite mixed structure. The 0.3ZnFe2O4-0.7SmFeO3 nanocomposite showed a substantial red shift in absorption edge with narrow band gap of ~1.8 eV. Further, photodegradation of prepared nanocomposite was assessed for the degradation of Methyl orange (MO). The 0.3ZnFe2O4-0.7SmFeO3 photocatalyst showed effective photodegradation for MO under direct sun light irradiation.
