Abstract

Degradation of catechol in visible light assisted heterogeneous electro-Fenton catalyzed by nano-Fe3O4 was study and the effects of operational parameters such as current density, temperature, illumination intensity and catalyst dosage on degradation performance were investigated respectively. The prepared nano-Fe3O4 catalyst was characterized with SEM, XRD et. al. Efficient degradation performance was obtained in this visible light assisted heterogeneous electro-Fenton system. The relationship between apparent rate constant and catalyst dosage at lower values exhibited high relativity. The interface reaction mechanism was dominant in this heterogeneous system catalyzed by nano-Fe3O4 based on the normalization of apparent rate constant and thermodynamics analysis. In addition, the stability and reusability of the prepared catalyst was tested via successive bath experiments.
