The layered polysilicate kanemite can be used to synthesize the novel mesoporous silica KSW‐2 (see picture), which contains square channels. The individual silicate sheets of kanemite are bent during the gradual leaching of hexadecyltrimethylammonium (C 16 TMA) surfactants from a layered C 16 TMA–kanemite complex.
