Abstract

Flower-like Co₃O₄/Fe₃O₄ magnetic microspheres were prepared by coprecipitation of Fe²⁺ and Fe³⁺ in presence of flower-like Co₃O₄ microspheres as template. The preparation process included three steps: preparation of flower-like Co₃O₄ microspheres by hydrothermal method; immersion of Fe²⁺ and Fe³⁺ ions; coprecipitation in the presence of OH^-. Rhodamine B (RhB) was chosen as model pollutants to investigate the photodegradation capacities of Co ₃O₄/Fe₃O₄ magnetic microspheres. The results showed that the microspheres exhibited excellent degradation property and can be recycled to use again. After four times use the degradation efficiency was still above 90%.
