Organosilane templated mesoporous titania

摘要

The present invention provides a convenient and reproducible method for development of high surface area (216 - 361 m2/g) mesoporous anatase titania particles of tunable pore (2.2 - 4.6 nm) using a novel organosilane template as a surface directing agent through evaporation induced self assembly. The synthesized Ti02 nanostructure aggregates are irregular particles with size of 10 - 30 nm. These mesoporous crystalline materials have been used after template removal for the fabrication of photoanode for DSSCs and a power conversion efficiency of 5.58 % is obtained which is significantly higher than the commercial P25 (3.5 %).
