METHOD FOR MANUFACTURING ORGANIC-INORGANIC HYBRID COMPOUNDS FOR CARBON DIOXIDE CAPTURE WITH AMINE GRAFTED HOLLOW MESOPOROUS SILICA PARTICLE

摘要

The present invention relates to a method of preparing an organic-inorganic hybrid compound for capturing carbon dioxide, and more particularly, to a method of preparing an organic-inorganic hybrid compound for capturing carbon dioxide including the following steps: surface-modifying a hollow mesoporous silica particle by using an alkoxysilane under the presence of a solvent to prepare a hollow mesoporous silica particle having a surface modified by an amine group; making the hollow mesoporous silica particle having the surface modified by the amine group, alkoxysilane, and a diol to sol-gel react under the presence of a catalyst to prepare an organic-inorganic hybrid precursor; and adding a photoinitiator to the organic-inorganic hybrid precursor to perform spin coating and then irradiating the organic-inorganic hybrid precursor with light to perform cross-linking.
