Hygroscopic Mg(OH){sub 2} gel was topotactically decomposed on TiO{sub 2} particle surfaces, resulting in highly nanoporous MgO-coated TiO{sub 2} particles. The highly hygroscopic and nanoporous MgO shell absorbed more water molecules and hydroxyl groups from the environment to yield an improved photocatalytic property of the core-shell particles as compared to the uncoated TiO{sub 2} counterpart.
