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

Abstract

Herein, the NiFe2O4/CeO2 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% CeO2 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 CeO2 phase. This study can guide the development of alternative photocatalyst for photocatalytic degradation of wastewater.
