摘要

The present work reportes the pertinence of samarium (Sm) doped spinel nanoferrites as magnetically recoverable photocatalyst for the removal of organic pollutants from wastewater. Thus, a series of Sm substituted spinel nanoferrites, MSmxFe2-xO4 (M=Ni, Co;x=0, 0.02, 0.06, 0.1) were synthesized via sol-gel methodology. The effect of Sm doping on the structural, morphological, optical and magnetic properties of pristine nanoferrites was investigated systematically. Further, the fabricated samples were explored as photocatalysts for the oxidative degradation of antibiotics (ofloxacin and norfloxacin) and dyes (methyl orange and safranin O). The Sm doped nanoferrites exhibit astonishing catalytic efficacy that can be attributed to higher surface area, octahedral site preference of Sm ions and reduced band gap. The syn-thesized nanoferrites display excellent recyclability which enables them to be utilized as potential photo-catalysts for wastewater treatment.
