Template-assisted Self-assembly and Cobalt Doping of Ordered Mesoporous Titania Nanostructures

Template-assisted ordered self-assembly of porous titania nanocrystals is shown to generate a face centered cubic structure where the walls of the pores are made of anatase nanocrystals ca. 8 nm in diameter (see Fig.). The walls of the pores can be doped with cobalt by solution infiltration without blocking the interconnected pores, which suggests that the material is likely to be an excellent supporting material for catalysis.
