August 2010Materials with tailored porosity can be prepared by templating methods. The left image shows a SiO2 (SiO2) material, consisting of fused spherical particles. A carbon replica (C) can be obtained as follows: (1) Infiltration of the SiO2-Material by a carbon precursor (e.g. sucrose solution), (2) Carbonization and (3) template removal by acid treatment. The pore size of the carbon replica corresponds to the particle size of the silica template. This principle can be also used to prepare porous materials on the nanometer scale.
