MANUFACTURING METHOD ATTACHED SILANE FUNCTIONAL GROUP FOR HEXAGONAL AND CUBIC MESOPOROUS SILICA MATERIALS AT ROOM TEMPERATURE

摘要

The present invention relates to a method of preparing a mesoporous silica material attached with a silane-based functional group, the method including the steps of: (a) mixing H_2O with EtOH at a predetermined ratio; (b) adding a surfactant to a solution in which H_2O is mixed with EtOH at a predetermined ratio; (c) adding one compound selected from the group consisting of a precursor and a silane-based functional group of the mesoporous silica material to the solution formed in the step (b) to stir the compound in the solution at room temperature for a predetermined time; (d) adding ammonia water to the solution stirred in the step (c) and stirring ammonia water in the solution for a predetermined time; (e) filtering the material synthesized in the step (d), and then washing and drying the filtered synthesized material; and (f) calcining the resulting material obtained after performing the step (e). The present invention provides a method of being capable of improving adsorption capability according to structures by providing a method of preparing a mesoporous silica material attached with a silane-based functional group, thereby enlarging specific surface area of the mesoporous silica material, and the present invention provides a preparation method of being capable of further increasing the adsorption amount by enabling carbon dioxide to be chemically bonded by functional groups attached to the surface of a mesoporous silica adsorbent.
