Hydrothermal synthesis of Cu-Fe3O4 nanocomposites towards catalytic degradation of organic dyes

Degradation of hazardous organic dyes utilizing multifunctional catalytic materials is supposed to be an efficient and promising method. Here, homogeneous Cu-Fe3O4 nanocomposites are synthesized through a facile and versatile one-pot hydrothermal method. The prepared Cu-Fe3O4 possesses spherical structure with rough surface and average diameter of 230 nm. High catalytic activity and structure stability make Cu-Fe3O4 nanocomposites effectively degrade rhodamine B, methylene blue, methyl orange, and congo red. The existence of magnetic Fe3O4 leads the nanocomposites to separate from the solution through external magnet and reuse for cycle degradation. And during the cyclic utilization, Cu-Fe3O4 nanocomposites keep high catalytic activity and, thus, could be used as an efficient degradation catalyst for the application of organic dyes.
