• Abstract:Degradation of hazardous organic dyes utilizing multifunctional catalytic materials is supposed to be an efficient and promising method. Here, homogeneous Cu-Fe<inf>3</inf>O<inf>4</inf>nanocomposites are synthesized through a facile and versatile one-pot hydrothermal method. The prepared Cu-Fe<inf>3</inf>O<inf>4</inf>possesses spherical structure with rough surface and average diameter of 230 nm. High catalytic activity and structure stability make Cu-Fe<inf>3</inf>O<inf>4</inf>nanocomposites effectively degrade rhodamine B, methylene blue, methyl orange, and congo red. The existence of magnetic Fe<inf>3</inf>O<inf>4</inf>leads the nanocomposites to separate from the solution through external magnet and reuse for cycle degradation. And during the cyclic utilization, Cu-Fe<inf>3</inf>O<inf>4</inf>nanocomposites keep high catalytic activity and, thus, could be used as an efficient degradation catalyst for the application of organic dyes.
