Fabrication of Crystalline, Highly Ordered Three-Dimensional Silica Monoliths (HOM-n) with Large, Morphological Mesopore Structures

Highly ordered silica monoliths (see Figure) with three‐dimensional structures have been fabricated using microemulsion lyotropic liquid crystal phases of Brij 56 as templates under acidic conditions, without loss of the mesoscopic order. The results reveal that the synthetic methodology can effecti...

Description
Summary:Highly ordered silica monoliths (see Figure) with three‐dimensional structures have been fabricated using microemulsion lyotropic liquid crystal phases of Brij 56 as templates under acidic conditions, without loss of the mesoscopic order. The results reveal that the synthetic methodology can effectively control the 3D mesopore morphology. Crystalline, millimeter‐sized particles and various geometrical cubic phases have been synthesized.
