Casting silica nets : By repeated “nanocasting” it is possible to first obtain a negative of the SBA‐15 structure, known as CMK‐3, which is then used to produce another nanocast by impregnation with tetraethoxysilane and condensation. After calcination to remove the carbon, an ordered mesoporous silica is obtained, called NCS‐1 (see scheme). This pathway could be generalized to allow also the synthesis of other ordered oxides.
