Abstract

The AgPO/CoFeYO nanocomposite with magnetic properties was simply synthesized by the hydrothermal method. The structure and morphology of the prepared material were characterized, and its photocatalytic activity for degradation of the methylene blue and rhodamine B dyes was also tested. It was revealed that the AgPO in the nanocomposite exhibited a smaller size and higher efficiency in degrading dyes than the individually synthesized AgPO when exposed to light. Furthermore, the magnetic properties of CoFeYO enabled the nanocomposite to possess magnetic separation capabilities. The stable crystal structure and effective degradation ability of the nanocomposite were demonstrated through cyclic degradation experiments. It was shown that AgPO/CoFeYO-0.2 could deliver the highest activity and stability in degrading the dyes, and 98% of the dyes could be reduced within 30 min. Additionally, the photocatalytic enhancement mechanism and cyclic degradation stability of the magnetic nanocomposites were also proposed.

摘要

通过水热法简单合成了具有磁性的AgPO/CoFeYO纳米复合材料。对制备材料的结构和形貌进行了表征，并测试了其对亚甲基蓝和罗丹明B染料降解的光催化活性。结果表明，纳米复合材料中的AgPO在光照下比单独合成的AgPO尺寸更小，染料降解效率更高。此外，CoFeYO的磁性使纳米复合材料具有磁分离能力。通过循环降解实验证明了纳米复合材料具有稳定的晶体结构和有效的降解能力。结果表明，AgPO/CoFeYO-0.2在染料降解方面具有最高的活性和稳定性，30分钟内可使98%的染料降解。此外，还提出了磁性纳米复合材料的光催化增强机理和循环降解稳定性。
