ZnO nanorod arrays (NRAs) were synthesized via magnetron sputtering and a low temperature aqueous solution growth in a short period time. The morphology and crystal structure were characterized by scanning electron microscopy (SEM), and X-ray diffraction (XRD). The ZnO NRAs were applied to conduct photo degradation of endocrine disrupting chemicals (EDCs) such as estrone (E1), 17 beta-estradiol (E2), 17 alpha-ethinylestradiol (EE2), and bisphenol A (BPA). The results indicate that ZnO NRAs exhibited different performances in dealing with various EDCs but do not have selectivity for a multicomponent mixture.
