Abstract Colloidal crystal templating method is a promising method to fabricate three-dimensional ordered macroporous (3DOM) materials. The method usually involves three steps, namely, assembly of template from uniform monodispersed beads, deposition of desired precursor inside the template and finally removal of the template. Each step has significant effect on the structure formation of the 3DOM materials. By this method, a number of such 3DOM materials have been prepared including simple oxides, ternary oxides, chalcogenides, non-metallic and metallic elements, alloys, hybrid organosilicates, and polymers. Such 3DOM materials hold the merits of both functional character of solid materials and ordered macroporous structure. They have potential applications in the fields such as photonic crystals, catalysts, supports, sensors, and battery materials et al. In this paper, the strategies for fabrication of 3DOM materials by colloidal crystal templating method and applications of 3DOM materials are briefly reviewed.
