Mesoporous TiO2–Ag composite particles with raspberry-like morphology were prepared by a two-step chemical route and their photocatalytic
and bactericidal properties were examined . Ag nanoclusters of about 50 nm in diameter were decorated on surface of submicrometer , anatase
TiO2 particles with Ag concentration of 3.870.4 at%; in which, the TiO2 particles were mesoporous with an average pore diameter of 9.3 nm
and a BET surface area of 147.5 m2 g1.
