increasing concern due to their frequent appearance and persistence in aquatic ecosystem and the threat to_x000D_
health and safety of aquatic life, even at trace concentrations. Conventional water treatment processes are_x000D_
known to be generally inadequate for the elimination of these persistent contaminants. Studies have_x000D_
demonstrated that about 64% of EDCs are removed by less than 50% while 9% are not removed at all by_x000D_
conventional biological treatment processes. Therefore, the development of efficient and sustainable removal_x000D_
methods for these emerging contaminants is essential. TiO2 is the most widely used photocatalyst for removal_x000D_
of organic contaminants from water. However, the higher efficiencies of ZnO compared to TiO2 for_x000D_
elimination of organic contaminant has been reported in several studies. Photocatalytic removal of EDCs by_x000D_
using zinc oxide photocatalyst (ZnO) is a promising process due to the unique characteristics of this_x000D_
photocatalyst such as wide band gap, non-toxicity and low cost. Recently, a considerable effort has been made_x000D_
to improve the photocatalytic performance of ZnO by doping with elements and narrowing band gap in order to_x000D_
be activated under visible light irradiation. However, any effort to narrow the band gap of semiconductors leads_x000D_
to the reduction of redox potential, as well as the efficiencies of elimination and mineralization. As an_x000D_
alternative strategy, surface modification is considered for enhancing the efficiency of adsorption and_x000D_
photocatalytic oxidation in this research. It is expected that surface fluorination of ZnO also enhances the_x000D_
photocatalytic degradation of emerging contaminants. Through building a partnership with the Dagua_x000D_
Technology Inc., this research is attempting to synthesize a dual functional hierarchical adsorbent/photocatalyst_x000D_
with high surface area and stability for removing EDCs from water with low energy consumption. For this_x000D_
purpose, a tubular photoreactor will be designed in this study to perform experiments for elimination and_x000D_
