One-pot synthesized NiFe2O4/CeO2 composite catalyst for efficient degradation of methylene blue via photocatalysis under visible light.

Herein, the NiFe 2 O 4 /CeO 2 composite photocatalysts were successfully synthesized via a facile one-pot hydrothermal method. We found that the one-pot synthesized composite photocatalysts exhibited better photocatalytic degradation performance than sole photocatalyst or conventional hand ground composite photocatalyst under visible light irradiation, and the degradation efficiency of methylene blue for the one-pot photocatalyst with 10% CeO 2 reached 82% in 10 h. The enhanced photocatalytic degradation performance can be explained by the improved adsorption and charge transfer of the reaction site induced by the CeO 2 phase. This study can guide the development of alternative photocatalyst for photocatalytic degradation of wastewater. The NiFe 2 O 4 /CeO 2 composite photocatalyst, synthesized by the novel one-pot hydrothermal technique, exhibits greatly improved photocatalytic activity towards methylene blue degradation due to the efficient synergistic effect induced by the spinel NiFe 2 O 4 phase and CeO 2 phase.
