A high activity photocatalysts N-ZnO has been synthesized by hydrothermal method. The characterization of the prepared N-ZnO nano-composite has been examined by SEm, TEm, ultraviolet-visible diffuse reflectance spectroscopy, X-ray diffraction, elemental analysis, Brunauer-Emmer Teller surface area. Under irradiation (>360 nm), N-ZnO shows high photocatalytic activity for the debromination of polybromo diphenyl ethers (pBDEs). The photocatalytic degradation kinetics of pBDEs has been investigated under different reaction conditions. The N-ZnO nano-composite exhibits excellent photostability after four run experiments. The possible photoreductive mechanism has been proposed. This study provides an efficient method to removal of halogen organic pollutants.
