Porous C-TiC biomorphic ceramic was derived from sea wool sponges by simple infiltration and heat treatment methods. During annealing, the sponge was converted to carbon templates, and it reacted with the infiltrated Ti-contained metalorganic solution to form C-TiC. The porous structure of sea wool sponge was retained in the final C-TiC product. Hollowed TiO2 scaffold was also produced by postannealing of the as-prepared C-TiC ceramic in air.
