Various layered double hydroxides (LDHs) consisting of magnesium and a trivalent metal (Al, Ga or In) in an Mg/M(III) ratio of 3 were prepared by precipitation from the corresponding nitrates and also from magnesium ethoxide and the acetylacetonates of the trivalent metals using the sol-gel method.
Titania-silica composite nanoparticles were prepared by sol-gel-hydrothermal and sol-gel routes, respectively, and their physicochemical and photocatalytic properties were compared. The results of XRD, TEM and BET surface areas showed that sol-gelhydrothermal route led to anatase titania-silica comp
