A soft and simple photochemical technique is proposed for the incorporation of copper oxide to nanoporous TiO 2 with the purpose of sensitizing the TiO 2 to wavelengths in the visible range. An aqueous solution of copper formate is employed as precursor. The light intensity value needed for the process, as well as its spectral range, is readily attainable with solar light. Because...
TiO 2 films were deposited on either glass or Si substrates by using a two-step soft-solution method. A submonolayer of anatase TiO 2 nanocrystals was first deposited on the substrate by a drain-coating process that was performed at 333 K from an aqueous TiO 2 colloidal solution. The substrate partially covered with the TiO 2 nanocrystals was immersed in an aqueous...
