Macroemulsions stabilized solely by nanoparticles of modified silica are used to prepare porous silica solid materials (see Figure), following slow evaporation of the two liquids. Both oil‐in‐water and water‐in‐oil emulsions can be employed, and the average pore size is close to the original emulsion drop diameter. Spherical or bicontinuous‐like pores may form, depending on the properties of the template emulsion.
