Source abstract
Abstract
Abstract Ternary magnetic Fe 3 O 4 nanowire@CeO 2 /Ag nanocomposites have been firstly synthesized by means of hydrothermal and co–precipitation techniques, and their ability to adsorb, photocatalytic degradation organic pollutants, methylene blue present in water, and separate, has been demonstrated. The results show that CeO 2 and Ag nanoparticles are uniformly deposited on the surface of Fe 3 O 4 nanowires. The photocatalytic experiments demonstrate that the Fe 3 O 4 @CeO 2 /Ag nanocomposites exhibit remarkably enhanced photocatalytic properties and stability compared to CeO 2 , CeO 2 /Ag, Fe 3 O 4 @CeO 2 , Fe 3 O 4 under natural sunlight exposure. Moreover, excellent photocatalytic degradation efficiency for phenol and MO are also observed. The enhanced photocatalytic performance may be attributed to the synergetic effect of Fe 3 O 4 nanowire, CeO 2 and Ag nanoparticles, which lead to the enhanced light harvesting, the promoted charge separation and enhanced adsorption capacity. In addition, the Fe 3 O 4 @CeO 2 /Ag photocatalyst can be easily collected and separated by an external magnet. These results suggest that the nanocomposites could be exploited as potential candidates for solar photocatalysis.
