There have been intensive efforts to develop synthetic materials with multiscale structural ordering that will mimic those of natural materials. In this paper, we report the synthesis of hierarchically ordered ceramics produced by in-situ mineralization of ordered wood cellular structures with surfactant-templated sol-gel solutions. As far as we know, this is the first time to successfully synthesize a hierarchical porous ceramic material that not only entirely reproduces the cellular structure of the biological tissue, but also contains organized nanoporous channels in the cell walls. This approach allows faithful reproduction of the cellular structures to amazing details.
