A stainless steel mesh was applied to the cathode of an electro-Fenton system. Methylene blue (MB) solution was chosen as the model waste water with non-biodegradable pollutants. For the model waste water, the degradation efficiency was compared among various SUS mesh cathodes with different surface treatments and magnetite coatings on them. With increasing amount of the magnetite coating on SUS mesh, the degradation efficiency also increased. The improved electro-catalytic characteristic was explained by the increased amount of in situ generated hydrogen peroxide near the cathode surface. Cyclic voltammetry data also showed improved electro-catalytic performance for SUS mesh with more magnetite coatings on them.
