Ni introduction induced non-radical degradation of bisphenol A in spinel ferrite/H2O2 systems

Abstract

Herein, we achieved reactive oxygen species manipulation using transition metal spinel ferrites (Ni_xCo_1−xFe₂O₄, x = 0, 0.5, 1) as Fenton-like agents. Specifically, NiFe₂O₄ mainly produced ¹O₂ and high-valence metals, while CoFe₂O₄ mainly produced ˙OH, from H₂O₂ activation. With bisphenol A as a model pollutant, the NiFe₂O₄/H₂O₂ system exhibited good resistance to ion interference.
