There are obvious advantages of mesoporous materials having macroporous structure, such as high surface area induced from mesoporous structures and easy access to active sites derived from macroporous structures. In this regard, these materials should be attractive for their application in the fields of adsorption, catalysis and separation. The macrostructured mesoporous materials were prepared by a new dual-templating method. Monodispersed micron-sized polystyrene (PS) beads were added directly to a gel solution prepared for the synthesis of mesoporous materials. Macroporous structures were observed by SEM, the mesoporous structures were characterized by XRD patterns and N2 adsorption analysis, and macropores and mesopores were observed by TEM. Our group applied these materials to several catalytic reaction, such as VOCs adsoption, HC-SCR, and HDS. |
