Preparation and Application of Macroporous Materials

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.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 materialsby colloidal crystal templating method and applications of 3DOM materials are briefly reviewed.
