摘要

The present invention relates to a method for preparing an organic-inorganic hybrid silica gel comprising the steps of: (1) preparing an organic-inorganic hybrid silica gel; And a step (step 2) of irradiating the organic-inorganic hybrid silica gel prepared in the step 1 with a radiation having an irradiation energy of 1 keV to 10 MeV after immersing the organic-inorganic hybrid silica gel in a solution containing the silver precursor, Organic-inorganic hybrid silica gel. In the method for producing an organic-inorganic hybrid silica gel impregnated with silver nanoparticles according to the present invention, silver nanoparticles reduced from a silver precursor solution by irradiating an electron beam are irradiated not only on the surface of the organic-inorganic hybrid silica gel, It can be impregnated as a whole. In addition to adsorbing organic iodine and gaseous iodine by introducing amines and thiol-based ligands known to be frequently used to remove carbon dioxide (CO ₂ ), hydrogen (H ₂ ) and inert gases, silver nanoparticles Iodine, iodine-related aerosols and iodine By adsorbing ions (I ^- ) at the same time, they have differentiation and superiority from other known adsorbents. Further, while the adsorbents are conventionally used once, the material prepared by the process of the present invention is an adsorbent that can be recycled several times.
