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 hexadecyltrimethyl-ammonium (C16TMA) surfactants from a layered C16TMA-kanemite complex.
