摘要：Photocatalytic degradation by efficient and easy recyclable semiconductor-catalysts is an ideal way to solve the environmental problem. A series of Fe2O3/Polystyrene (Fe2O3/PS) composite fibers with hydrophobic property were obtained by the electrospinning and γ-Ray irradiation methods. The γ-Ray irradiation treatment not only formed steady micro-nano construction of nanoparticles and fiber, but also reduced the hydroxyl group on Fe2O3 surface. The high photocatalytic efficiencies of Fe2O3/PS fiber were discovered with the high content of 4-chlorophenol (4-CP) and 4-nitrophenol (4-NP), due to the synergetic effect of adsorption and degradation. The suitable adsorption capacity of Fe2O3/PS could promote the utilization of the generated hydroxyl radical(OH[rad]) to directly oxidize the adsorbed pollutant molecules. Additionally, the photocatalytic activities for 4-CP and 4-NP still reached 80% and 75% in the 6th cycling and the composite fiber exhibited the good recyclability, which has the application development prospect for wastewater treatment. The mechanism of 4-CP and 4-NP decomposition was verified. Hence, the gained results could provide some insights into phenol degradation over the multifunctional and efficient catalyst. ? 2019 Elsevier B.V.
