Patent ID: 8747793

Claim:
A method for manufacturing a hollow sphere with a mesoporous structure, comprising the following steps: (A) providing an alkaline solution of mixed surfactants, wherein the mixed surfactants comprises a cationic surfactant and a non-ionic surfactant, the cationic surfactant is represented by the following formula (I), and the non-ionic surfactant is represented by the following formula (II): R 4 —(OC 2 H 4 ) n —OH (II), wherein, each R 1 and R 2 independently is a C 1 -C 3 alkyl group, R 3 is a C 12 -C 22 alkyl group, R 4 is a C 12 -C 22 alkyl group, and n is an integer ranging from 2 to 20; and (B) adding a silane precursor and at least one functional silane precursor into the alkaline solution of the mixed surfactants and the functional silane precursor to form a hollow sphere with a mesoporous structure, wherein the hollow sphere comprises a shell with plural mesopores penetrating both surfaces of the shell, and the silane precursor and the functional silane precursor are respectively represented by the following formula (III) and formula (VII): Si(OR 5 ) 4 (III) wherein R 5 is a C 1 -C 3 alkyl group; and R 6 -Si(OR 7 ) 3 (VII) wherein, R 6 is 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, X is Cl, Br, or I, and each R 7 independently is a C 1 -C 3 alkyl group.
