Investigation of Tetracycline Removal from Aqueous Environments via Bio-Electro-Fenton Process Using an LDH/CN Cathode

The integration of CuFeMn-Layered Double Hydroxide (LDH) with graphitic carbon nitride (g-C3N4), designated as CFM/CN, was identified as a potential strategy to enhance the photogeneration of hydrogen peroxide (H2O2) and improve the photoelectrocatalytic performance within a Bio-Electro-Fenton (BEF) system. The CFM/CN-BEF system is anticipated to broaden the applicable pH range and augment the overall efficiency of the BEF process, thereby facilitating more effective removal of antibiotics from wastewater. This investigation will systematically evaluate the removal efficiency of tetracycline (TC) as a representative recalcitrant pollutant under a wide range of pH conditions. The findings are expected to provide novel insights into the degradation mechanisms of TC and advance the fundamental understanding of BEF technology for treating refractory organic wastewater.
