The synthesis of metal oxide nanosheets using a lamellar phase as a template effectively modified the nanosheets because surfactant molecules surround the entire surface of the nanosheets. Here, we show the development of layered titanate nanosheets with a lamellar mesostructure. The layered titanate nanosheet forms by using the lamellar self‐assembly of cationic dodecanediamine as a template and an electrostatic interaction between negatively charged titanate nanosheets and positively charged 1,12‐dodecanediamine during hydrothermal synthesis. This approach leads to titanate nanosheets with new properties such as visible light absorption and a high adsorption of cationic organic compounds, which results in the effective photodegradation of Rhodamine B under visible‐light irradiation. This approach has important implications for the use of metal oxide nanosheets in environmental and industrial applications.
