Transparent TiO2 nanosheet thin films were prepared using layer-by-layer method with poly(diallyldimethylammonium chloride) as a counter polymer. The possibility of photocatalysis by the light in the long wavelength range was examined by grafting Cu on the film. Photocatalytic decomposition activity for gaseous 2-propanol under UV illumination without light for electron excitation of TiO2 nanosheet was increased by Cu grafting, suggesting that the interfacial charge transfer mechanism is effective also for nanosheet films.
