Photocatalytic activity of TiO₂ foams

Abstract

The specific surface and pore size distributioin of TiO₂ photocatalysts are essentially important for purification and detoxification of water and air. We developed TiO₂ foams having high specific surface area about 120 m²/g and controlled open pores. We found that the structure of TiO₂ foams was effective in the photocatalytic activity for decomposition of acetaldehyde.
