Abstract

The Ag₃PO₄/CoFe_1.95Y_0.05O₄ 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 Ag₃PO₄ in the nanocomposite exhibited a smaller size and higher efficiency in degrading dyes than the individually synthesized Ag₃PO₄ when exposed to light. Furthermore, the magnetic properties of CoFe_1.95Y_0.05O₄ 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 Ag₃PO₄/CoFe_1.95Y_0.05O₄-0.2 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.
