Abstract
A method for synthesizing a phosphonic acid functionalized mesoporous metal oxide material (e.g., silica, titania, alumina, preferably silica material) is provided. Further, a method of using the phosphonic acid functionalized mesoporous silica material as a solid acid catalyst in a pinicole-pinacolone rearrangement reaction, and a method of using a phosphonic acid functionalized mesoporous silica material as a solid acid catalyst in a transesterification reaction is provided. A method for preparing a mesoporous titania film for use in a dye sensitized solar cell is also provided.
Claims7
A method for synthesizing a phosphonic acid functionalized mesoporous silica material comprising the steps of:
- (a) synthesizing a phosphonated triblock copolymer template;
- (b) self-assembling said phosphonated triblock copolymer with tetraethyl orthosilicate to form a mesoporous silica material attached to said phosphonated triblock copolymer template;
- and
- (c) extracting at least a portion of said mesoporous silica material from said phosphonated triblock copolymer template to form said phosphonic acid functionalized mesoporous silica material.
