“…If pore connection among the closed interior pores in an ordered mesoporous structure occurs, the closed interior pores become open pores, thereby increasing the effective specic surface area while maintaining a relatively high mechanical strength. 20 Several attempts have been made to increase the effective surface area via interior pore connection. These attempts have including exposing pores by grain growth, 21 the generation of cracks by thermal shock, 22 and adding large amounts of surfactant.…”

The structural and gas sensing properties of mesoporous Sr 0.9 La 0.1 TiO 3 films for oxygen sensing applications were investigated as a function of surfactant concentration. Through the synthesis of Sr 0.9 La 0.1 TiO 3 with a mesoporous structure, the surface area and pore connectivity were increased by increasing the surfactant concentration. Using a thermal treatment, interior pores were exposed to the surface thereby increasing the surface area. This increase in surface area induces an increase in oxygen absorption, which results in an enhanced oxygen sensitivity. The oxygen sensing properties of mesoporous Sr 0.9 La 0.1 TiO 3 films were analyzed at an oxygen concentration of 30% and an analysis temperature of 550 C. The results at these conditions showed the maximum oxygen sensitivity (9.43), response time (38 s), and recovery time (181 s). The inclusion of a surfactant during the preparation of mesoporous films was found to be a simple and effective method to enhance the surface area and interior pore connectivity of the films to enhance their gas sensing performance.

“…Therefore, the introduction of an open pore structure by increasing the pore connectivity in ordered mesoporous TiO 2 films is necessary to utilize their high specific surface area, which is a great advantage of ordered mesoporous films because the pore connectivity can enhance the permeability of films consisting of only close pores. 10 The enhanced pore connectivity in ordered mesoporous TiO 2 offers a high surface area and density of surface active sites. Therefore, they are great candidates for application as gas sensors with high sensitivity and relatively strong mechanical properties.…”

In this work, ordered mesoporous TiO 2 films with interior pore connections were fabricated. To introduce the interior pore connections, the grain growth of TiO 2 on the pore wall structure was controlled by increasing the annealing time. In the annealing process, the growth of TiO 2 grains was enhanced, and interior pores were connected by a meso-channel formed during the growth of TiO 2 grains. As a result, with increasing annealing time, the specific surface area of the mesoporous TiO 2 films increased by a factor of 3, although the porosity decreased. When the ordered mesoporous TiO 2 film with enhanced pore connectivity was applied in a CO gas sensor, the gas sensitivity increased by a factor of almost 20 due to the enhanced pore connectivity resulting from controlled annealing time. The introduction of pore connectivity in a closed pore structure may be an advantageous method in various fields where a large surface area is required for nanoporous structured materials.) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.
