Preparation method of inorganic hierarchical pore structure material
The invention provides a preparation method of an inorganic hierarchical pore structure material. According to the method, functionalization and quaternization are carried out on a three-dimensional ordered macroporous cross-linked polystyrene material; ethyl orthosilicate or tetrabutyltitanate conducts in situ hydrolysis on the amino group to form silicon dioxide or titanium dioxide; and finally the cross-linked polystyrene is removed by a high-temperature calcination method, thereby preparing an inorganic hierarchical porous material. The preparation method of the invention can avoid use of expensive polymer soft template, has the advantages of simple and easy operation and stable pore structure of the product, and shows the superiority in the preparation of hierarchical pore structure materials.
