摘要：

A magnetic separable photocatalyst based on Fe3O4/Bi2O2(OH)(NO3) was synthesized using a two-step method based on co-precipitation and a hydrothermal route. The photocatalytic activity of the prepared Fe3O4/Bi2O2(-OH)(NO3) for degradation of rhodamine B (RhB) dye under natural sunlight irradiation was investigated. The 3% Fe3O4/Bi2O2(OH)(NO3) photocatalyst, comprising 3 mol% of Fe3O4, showed high efficiency (about 98.7%) after 120 min of photo illumination. The photogenerated holes played a prominent role in the photodegradation of the dye. The present finding demonstrated the enhancement of photocatalytic performance using the fabrication of a novel, sunlight-active photocatalyst with a low electron-hole recombination rate at the interface.
