摘要: Abstract Magnetic NiFe 2 O 4 /BiOBr composites with enhanced photocatalytic activity for degradation of Rhodamine B were synthesized by a simple one-pot combustion method. The structures, morphologies, optical, magnetic and visible-light properties as-prepared samples characterized. Experimental results showed that different molar ratios to BiOBr (0–0.2) successfully obtained. photodegradation performance photocatalysts gradually increases increasing ratio /BiOBr. composite mole 0.2 shows the best B, which can be ascribed efficient separation photo-generated electrons holes. ensure using magnet. Moreover, no obvious deterioration was observed after six-cycle experiments.
