Fe- or Ni-substituted titania nanosheets have been synthesized by chemically exfoliating precursor layered titanates into colloidal single sheets. Obtained nanosheets were self-assembled via consecutive adsorption with polycations to produce multilayer ultrathin films, which exhibit photocatalytic properties. In the case of Fe system, UV absorption band was widened towards the visible light region in comparison with that of titania nanosheets of Ti0.9O2. (C) 2002 Elsevier Science B.V. All rights reserved.
