We report a simple, low-cost methodology for unprecedentedly enhancing the photocatalytic
activity of layered inorganic semiconductors. A layered titanate with a lepidocrocite-type
structure scarcely showed photocatalytic activity for a test reaction, the oxidative
decomposition of formic acid in water into CO2, under simulated solar light, but it showed
highly enhanced photocatalytic activity upon mixing with a much smaller amount
(approximately 10 wt%) of commercially available TiO2 nanoparticles (P25) in water. The …

… Title: Unprecedentedly enhanced solar photocatalytic activity of a layered titanate simply
integrated with TiO2 nanoparticles This work reported a simple, low-cost methodology for
unprecedentedly enhancing the photocatalytic activity of layered inorganic semiconductors.
A layered titanate with a lepidocrocite-type structure scarcely showed highly enhanced
photocatalytic activity upon mixing with a much smaller amount of commercially available
TiO2 nanoparticles in water due to the transfer of photoexcited electrons from the layered …
