Abstract

Oxygen vacancy-rich FeCo 2 O 4 @SnO 2 (FCO@SnO 2 ) hexagonal nanorods were synthesized via an aging-mediated calcination process. The photocatalyst demonstrated exceptional photo-Fenton degradation efficiency, achieving 98.3 % sulfamethoxazole (SMX) degradation under visible light irradiation. The enhanced activity can be attributed to the efficient charge separation and transfer, and the dominant (111) facet exposure in FeCo 2 O 4 could amplifies the generation of reactive oxygen species (ROS). Additionally, the oxygen vacancy in FeCo 2 O 4 effectively traps electrons , minimizing recombination and further enhancing photocatalytic efficiency. The photocatalyst exhibits a high surface area of 155.18 m 2 /g and…
