From: Enhanced photocatalysis by coupling of anatase TiO2 film to triangular Ag nanoparticle island

Figure 1

(a) SEM image of the PS colloidal crystal template; (b) SEM image of deposited Ag film coated PS spheres monolayer. The inset one is the magnification SEM image of (b); (c) SEM image of Ag NP island produced after removing the PS spheres monolayer; the inset one is a specially magnified Ag NP on the TiO2 film; (d) Schematic figure depicting the preparation of triangular metal NP island connected with semiconductor by PS lithography strategy, and the inset one is the cross sectional TEM image of Ag/TiO2 nanocomposite.
