Slit-width-controlled H₂Ti₄O₉/TiO₂ nanocomposites were fabricated by stirring with (C_nH_2n+1NH₃)₂ Ti₄O₉ and a titanyl acylate complex at 20 °C for 48 h followed by UV light irradiation from a 450 W high-pressure mercury lamp. (C_nH_2n+1NH₃)₂Ti₄ O₉ was synthesized by an intercalation reaction with H₂Ti₄O₉ and C_nH_2n+1NH₂ in aqueous or heptane solution for 48 h. The remaining C_nH_2n+1NH₂ and acylate after titania incorporation was completely decomposed into CO₂, H₂O, and NH₃ by UV light irradiation. A slit in the obtained nanocomposites was produced, and its width could be controlled by changing the carbon length of C_nH_2n+1NH₂. Furthermore, the slit expansion and the transformation of the layer structure to fiberlike TiO₂ were successfully confirmed by scanning electron microscopy photographs for the first time.
