Synthesis of core–shell structured Fe3O4@α-MnO2 microspheres for efficient catalytic degradation of ciprofloxacin

Abstract

Three-dimensional core–shell structured Fe₃O₄@α-MnO₂ microspheres were successfully fabricated by a two-step hydrothermal method. The obtained magnetic microspheres exhibit excellent ability to activate persulfate for catalytic degradation of ciprofloxacin in wastewater with easy magnetic separation.
