A new type of nanocomposites containing titania and gold were prepared via the coupling between exfoliated Ti0.91O2 nanosheets and surfactant-capped Au nanoparticles, followed by flocculation and calcination. After hybridization with Ti0.91O2 nanosheets, octahedral Au nanoparticles were embedded intimately into the matrix of titania, leading to a broad absorption peak assigned to surface plasmon resonance...
Self-assembled multilayer films of nitrogen-doped exfoliated titania nanosheets and Au nanoparticles (NP) were fabricated via layer-by-layer assembly method followed by solar irradiation treatment. Au NP were found to form by in-situ reduction and thus disperse homogeneously between nitrogen-doped titania nanosheet galleries and the composite films of disordered structure, as confirmed by transmission...
