Synthesis of hierarchically ordered ceramic materials with wood cellular structures has been developed by an in-situ mineralization of ordered wood cellular structures with surfactant-templated sol-gel solution at different pHs. At low pH, a silicic acid coated onto inner surface of wood cellular structures and kept their structures open to form a positive replica after calcination of wood contents, while at high pH, the precipitating silica particles due to fast condensation clog the empty cellular and pit structures to form a negative replica. The ceramic monoliths after calcinations contain ordered wood cellular structures, multi-layered cell walls, pits, and vessels well-preserved with positive or negative contrasts, respectively. The surfactant-templated mineralization not only helped structural integrity, but also produced hexagonally ordered nanoporosity in the cell walls after calcination.
