Ordered mesoporous TiO 2 films with increased pore connectivity are introduced in this work. Crack generation was accomplished by thermal shock using rapid thermal annealing to obtain a connected pore structure. Due to the increased pore connectivity caused by crack generation, the specific surface area of mesoporous TiO 2 films increased by 2.6 times. As specific surface area increased, gas sensing properties of the ordered mesoporous TiO 2 film were enhanced, thus, ordered mesoporous TiO 2 films with increased pore connectivity are ideal candidates for gas sensor applications.
