The present invention is directed to a process for preparing a porous material, at least comprising the steps of providing a gel comprising a solvent (S), wherein the solvent (S) has a volume (V1), pressurizing the gel with carbon dioxide at a temperature and a pressure at which carbon dioxide solubilizes in the solvent (S) forming gas-expanded liquid (EL), wherein the gas-expanded liquid (EL) has a volume (V2) and (V2) is greater than (V1); removing supernatant liquid, and drying the gel. The present invention further is directed to the porous material obtained or obtainable according to the process as such as the use of the porous material according to the invention in particular for medical, biomedical and pharmaceutical applications or for thermal insulation.
