Facile Synthesis of Flower-like Superparamagnetic Fe3O4/BiOCl Nanocomposites as High Effective Magnetic Recyclable Photocatalyst under Visible Light
Journal of Magnetics, Volume 21, Number 2, 30 Jun 2016, Pages 179-182
Abstract
In this paper, 10 nm Fe3O4 nanoparticles were modified on the surface of 2 μm flower-like bismuth oxychloride (BiOCl) spheres by a facile co-precipitation method. The results showed that the Fe3O4/BiOCl nanocomposites exhibited excellent photocatalytic activity and superparamagnetic property (Ms = 3.22 emu/g) under visible light for Rhodamine B (RhB) degradation. Moreover, the Fe3O4-BiOCl photocatalyst possessed magnetic recyclable property, which could maintain high photocatalytic effective even after 20 cycle times. These characteristic indicates a promising application for wastewater treatment.
