ZnO and g-C3N4 provide excellent photocatalytic properties for degradation of antibiotics in pharmaceutical wastewater. In this work, 2D-2D ZnO/N doped g-C3N4 (NCN) composite photocatalysts were prepared for degradation of tetracycline (TC), ciprofloxacin (CIP) and ofloxacin (OFLX). The addition of ZnO resulted in higher separation efficiency and lower recombination rate of photogenerated charge under visible light. The composite photocatalyst showed better degradation performance compared to ZnO or NCN alone. The TC degradation reached 81.3% in 15 minutes by applying the prepared 20% ZnO/NCN ...
