Abstract:

The possibility of prepared one-body catalyst was investigated for electro-Fenton reaction by coating magnetite nanoparticles powder on metal foams (Fe-Cr-Al foams). Up to 10 wt% magnetite could be coated onto metal foams with strong enough adhesion. An electro-Fenton system with a magnetite nano-particles�?? wash-coated Fe-Cr-Al foam as cathode and graphite as anode was successfully applied for the discoloration of methylene blue in aqueous solution for the first time. The effects of pH, applied voltage, supporting electrolyte, electrode inner space, and catalyst dosages were investigated and optimized. Using this cathode, methylene blue was removed with >99.8% removal rate at 10 ppm after 60 min and with >95.2% at 50 ppm after 120 min of reaction. Furthermore, those cathodes could be reused at least three times without performance degradation. Due to high degradation capability, simple recovery and high reusability, magnetite nanoparticles�?? wash-coated metal foams can be an effective cathode of electro-Fenton systems for the abatement of dyes in wastewater.
