The novel visible light-responsive photocatalytic materials are of great scientific significance in solving the pollution problem of antibiotics in wastewater. The use of sulfide as a photocatalyst in the degradation of waste water has been studied, but no report has been shown in the use of heterojunction materials based on metal sulfide and metal organic framework for degradation of antibiotic wastewater. In this project, the microemulsion technology is planning to be used to synthesize the metal sulfide / metal organic framework heterojunction materials and regulate interface to improve the ability of antibiotics degradation in wastewater. The microstructure, chemical composition and properties of the photocatalytic materials were characterized, and the internal mechanism of microemulsion regulation was discussed. Further, metal sulfides/MOF composites photocatalyst properties, including adsorption behavior, photocatalytic activity and anti-photocorrosion, will be comprehensively studied for elucidating the intrinsic mechanism of photocatalytic degradation of antibiotics. The photocatalytic mechanism will be elucidated by combining the free radicals, the intermediate products, the dynamically degrade process in solid-solution interface, the degradation dynamics and the transient change of photocatalyst. Finally, a photocatalytic reactor based on metal sulfide/MOF photocatalyst will be designed and applied to treat the real wastewater. In this study, it is expected to solve the uncontrolled synthesis-structure-performance of photocatalyst and the reaction mechanism of antibiotic in water-solid-microinterface under visible light irradiation. In a word, this study will provide the theory basis and practicable methods for pollutants control.
