Formation of a new Ia(3)over-bard cubic meso-structured silica via triblock copolymer-assisted synthesis
(2003) In Journal of the American Chemical Society 125(15). p.4402-4403- Abstract
- A new mesoporous silica structure with cubic Iad symmetry has been synthesized. The structure has very large unit cell dimensions, up to 250 Å in the as-synthesized form and 222 Å after calcination, and the surface area is around 700 m2/g. The syntheses were done according to well-established synthesis conditions with the triblock copolymers Pluronics P103 or P123, except for the addition of NaI to the synthesis mixture. Small-angle X-ray scattering revealed that the sample has Iad symmetry. According to electron micrographs, the structure is similar to that of MCM-48, and we thus propose that the structure lies on the gyroid minimal surface.
