摘　　要：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.Highly ordered mesoporous silica HOM-5 （cubic, Ia3d） with three-dimensional （3D） bicontinuous channels was fabricated under acidic condition via a direet-templating synthesis. Primary lyotropie 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 m^2.g^-1, respectively. Results show that materials obtained from this simple synthesis are highly ordered with perfect meso-struetures. The results of hydrothermal testing show that the as-synthesized silica retains Ia3d space group after refluxing in boiling water for 6 hours.
