  • Channel-type mesoporous silica material with elliptical pore section
    Publication number: 20100015027
    Abstract: A channel-type mesoporous material with an elliptical pore section has a 2D-rectangular pore arrangement. Besides, the channel-type mesoporous material includes silica and has a unit cell ratio a/b satisfying the inequality of ?{square root over (3)}<a/b?2.85. The synthesis procedure can be easily applied to prepare functional mesoporous silica materials, and examples given in this application are the syntheses of cyanoethyl-functionalized and mercaptopropyl-functionalized mesoporous materials with a c2mm symmetry. The mesoporous materials discussed herein have great potential for various advanced applications in the fields of catalysis, selective adsorption, controlled drug delivery and release, and many of other applications.

  • Method of fabricating nanostructured materials
    Patent number: 6733828
    Abstract: A method of confined synthesis of nanostructured material inside a mesoporous material. The method includes the step of providing mesoporous material having uniform and ordered mesopores. Next, a monolayer of charged functional group is attached on the pore surface of mesoporous host material by reacting with functional molecule. A oppositely-charged molecule is incorporated into the confined space of mesoporous material by either ion exchange or incipient wetness impregnation. Finally, the incorporated molecule is reduced or oxidized or further reacted with secondarily-incorporated molecule to form nanostructured material in mesoporous material.
