Abstract
Official abstract text for this publication.
The present invention relates to a hollow sphere with a mesoporous structure, and a method for manufacturing the same. The hollow sphere with a mesoporous structure comprises: a shell with plural mesopores penetrating the shell, wherein the shell comprises: a mesoporous silicon oxide material, and mesopores of the mesoporous silicon oxide material are arranged in Ia3d cubic symmetry. In addition, according to the method of the present invention, the aforementioned hollow sphere with the mesoporous structure can be easily obtained by use of mixed surfactants of a cationic surfactant and a non-ionic surfactant.
First claim
Opening claim text (preview).
What is claimed is: 1. A hollow sphere with a mesoporous structure, comprising: a shell with plural mesopores penetrating both surfaces of the shell, wherein the shell is a silicon dioxide material having orderly-arranged mesopores and further comprises surface-bound functional groups, which are selected from the group consisting of a C 1 -C 4 alkyl group, a C 1 -C 4 alkoxy group, —(CH 2 ) 1-3 —SH, —(CH 2 ) 1-3 —CN, —(CH 2 ) 1-3 —OCN, —(CH 2 ) 1-3 —X, —(CH 2 ) 1-3 —NH 2 , and —(CH 2 ) 1-3 —COOH, wherein X is Cl, Br, or I; and the mesopores of the silicon dioxide material are arranged in Ia3d cubic symmetry. 2. The hollow sphere with the mesoporous structure as claimed in claim 1 , wherein the surface-bound functional groups are —(CH 2 ) 1-3 —SH, or —(CH 2 ) 1-3 —CN. 3. The hollow sphere with the mesoporous structure as claimed in claim 1 , wherein the surface-bound functional groups are —(CH 2 ) 3 —SH, or —(CH 2 ) 3 —CN. 4. The hollow sphere with the mesoporous structure as claimed in claim 1 , wherein the particle size of the hollow sphere is 50-300 nm.
