Abstract:
In this study, we designed a novel combined electro-Fenton system for the treatment of wastewater containing biological recalcitrant using electric-field-induced ceria (CeO2) as the synergistic catalysts. It was found that by applying this CeO2 electro-Fenton system, the current efficiency improved from 74.49% to 109.82% within 2.5 min; the removal efficiency for dimethyl phthalate (DMP) increased from 85.5% to 94.9% within 20 min; and the mineralization rate increased from 76.01% to 93.58% after 120 min. The effects of parameters such as the applied potential, electrolyte, and concentration of Fe2+ on the current efficiency were systematically studied. Investigations by LSV, zeta titration, X-ray photoelectron spectroscopy (XPS), X-Ray Diffraction (XRD)and electron spin resonance (ESR)revealed the reasons for achieving a current efficiency of over 100% in the CeO2 electro-Fenton system. A mechanism that involved Brønsted acid sites and the redox cycle of sulfate CeO2 was proposed.

In the new picture, imagine that the first charge sets up an electric field independent of all other charges in the universe. When another charge comes in its vicinity, the second charge experiences an electric force depending on the electric field at that point. The source charge does not...
