Abstract: Abstract Microstructured porous silicas have potential applications in catalysis, separations, coatings, microelectronics and electro-optics, but methods for producing materials with uniform submicrometre pores have not been available. We have now developed a method in which modified colloidal crystals are used as templates for silica polymerization. This method yields products with highly uniform and structured pores of tuneable size in the submicrometre region.
