Abstract

The invention relates to a directional grown mesoporous adsorption material with a controllable structure and a preparation method thereof, and belongs to the technical field of porous adsorption materials. The adsorption material has an alumina-silica composite structure and is assembled by an inorganic-organic interface in an alumina hole, and the mesoporous structure is formed in a directional growing mode along the axial direction of an alumina array hole; and the mesoporous structure of a silica phase can be controlled as a regular and ordered two-dimensional or three-dimensional structure, and the pore canal growing direction and the aperture size of the mesoporous structure are modulated by adjusting and controlling a mixture ratio of a self-assembling system and assembling conditions. The adsorption material has the advantages that the adsorption material has an integral composite structure and is convenient to apply; the pore structure is regular and ordered, the size distribution is even, and the capillary condensation is quick; the porosity is high and the adsorbing capacity is large; and the surface property is adjustable, and the adsorption material is applicable to adsorption substances with different polarities. The adsorption material can be widely applied to quick high-capacity storage of liquid gas or gas solution.
