Abstract
Electro-Fenton system is an advanced application technology of oxide, hydroxyl radicals by self-cycle mode to the sewage degradation, but the overall performance of the application by the electricity production efficiency and the cathode sewage wastewater treatment impact. Therefore, carbon nanotubes (CNT) of the tubular structure and high specific surface area conductive base, applied of potassium hydroxide (KOH) by surface modification and polyvinylidene fluoride (PVDF) to stabilize forming the cathode plates, aiming to enhance the electro-Fenton system cathodic reaction rate of hydrogen peroxide and electrical plates. Experiments by linear voltammetry, contact angle measurements, four-point probe measurements and scanning electron microscopy (SEM) were measured characteristics of the cathode plate. The results show that upon activation of the cathode plate whose surface density again increased and the contact angle decreased by 31%, and hydrogen peroxide (H_2O_2) cumulative concentration of 39μM, It is seen from the present studies, CNT-PVDF after the activation of KOH plates can be used with the feasibility of microbial fuel cells.
