| Abstract: Highly ordered mesoporous silica HOM-5(cubic, Ia3d) with three-dimensional (3D) bicontinuous channels was fabricated under acidic condition via a direct-templating synthesis. Primary lyotropic liquid crystal mesophase of P123 was used as the template. The as-synthesized HOM-5 had thick walls of 15.0 nm. The mean pore diameter and specific surface area of the material were 5.7 nm and 500 m2·g-1, respectively. Results show that materials obtained from this simple synthesis are highly ordered with perfect meso-structures. The results of hydrothermal testing show that the as-synthesized silica retains Ia3d space group after refluxing in boiling water for 6 hours. |
