Abstract

The “polymerizable complex (PC)” technique, a kind of gel technologies, is based on formation of a polyester resin precursor in which various metal ions can be uniformly distributed keeping their initial stoichiometric ratio. The approach allows for the synthesis of multicomponent oxides at reduced temperatures. Feasibility of the PC method is demonstrated for the synthesis of BaTi4O9 at 700–900 °C. BaTi4O9 was subsequently converted to nanocomposite materials by modifying its surface with ultrafine particles of RuO2, and they were used as photocatalysts for decomposition of water into H2 and O2 under irradiation of light from a high-pressure Hg lamp operated at 100 W. High-resolution transmission electron microscopic observations indicates uniform dispersion of spherical RuO2 particles of ∼2 nm in diameter on the host BaTi4O9 surface. The nanocomposite BaTiO9/RuO2 (1 wt % Ru relative to BaTi4O9) material prepared by the PC method at 800 “C showed a photo-catalytic activity ∼3 times higher than that of a material prepared by the conventional ceramic technique at 1100 °C.
