摘要: A natural porous silica, pumice, was used as a substrate for photocatalytic TiO2. Mounting of anatase-type TiO2 successfully performed through hydrolysis TiOSO4 under hydrothermal conditions. Anatase-mounted pumice particles thus prepared were floating and rotating on the surface water with stirring. Adsorption performances examined in methylene blue aqueous solution dark ultraviolet ray irradiation, respectively. Methylene could be decomposed rapidly by anatase-mounted particles. Their photoactivity evaluated subtracting adsorbed amount blue. High efficiency usage UV rays photodecomposition organic pollutants expected.
