Along with the development of productive forces, the use of organic compounds including diversified dyes an‎d multiple drugs has become more an‎d more commonly, resulting in the accelerating water contamination. Herein in this paper, Au doped PCN 224 are designed as bi-functional wastewater treatment agents to absorb an‎d decompose organics molecules efficiently under light irradiation. After inser‎ted with Au, the PCN 224 nano particles, which is kind of porous, stable an‎d photosensitive metal-organic framework, show enhanced photo degradeability. Because the Au inser‎ted could inhibit the re-combination of electrons an‎d holes by absorbing photo-electrons; decrease the nanoparticles’ ban‎d gap, an‎d finally produce much more free radicals. In the meanwhile, due to the lower binding energy between S an‎d Au, the Au modified PCN 224 perform better in absorbing organic compounds consisted of S contained heterocyclic ring (such as methylene blue). This work provides new insights into the precious design of materials in clearing organic compounds.
