I. Pastoriza-santos et al., One-pot synthesis of Ag@TiO2 core-shell nanoparticles and their layer-by-layer assembly, LANGMUIR, 16(6), 2000, pp. 2731-2735
Silver nanoparticles coated with a uniform, thin shell of titanium dioxide
are synthesized via a remarkably simple one-pot route, where the reduction
of Ag+ to Ag-0 and the controlled polymerization of TiO2 on the surface of
silver crystallites take place simultaneously. The prepared dispersions of
coated nanoparticles display a surface plasmon band, which is significantly
red-shifted with respect to that of bare AK. High quality ultrathin films
of the core-shell clusters are prepared via layer-by-layer assembly. The na
noparticles are arranged in closely packed layers interlaced with polyelect
rolyte producing a stratified core-shell hybrid material with unique struct
ure and catalytic and electron-transport properties.
