| titleOfInvention | Bismuth-based functional material for adsorbing gaseous iodine and preparation method and application thereof |
| abstract | The invention relates to the technical field of nuclear fuel post-treatment, and discloses a bismuth-based functional material for adsorbing gaseous iodine and a preparation method and application thereof, wherein bismuth salt and polyacrylonitrile are dissolved in a solvent and mixed to form a precursor solution; carrying out electrostatic spinning to obtain a fiber membrane; and pre-oxidizing in an air atmosphere and carbonizing in an inert gas atmosphere to obtain the bismuth-based functional material. The material takes the carbon nanofiber membrane as a carrier, and the metal bismuth nanoparticles are uniformly attached to the fibers, so that abundant active sites are provided for chemical adsorption of iodine, the adsorption capacity of the material can reach 560mg/g, and the material can effectively adsorb and separate gaseous iodine. Meanwhile, the material is simple in preparation method and low in raw material cost, and more importantly, compared with most of powdery adsorbents, the material has a macro membrane morphological structure with good flexibility and high thermal stability, is expected to be applied to large-scale industrialization in the spent fuel post-treatment process, and has a wide prospect. |
