Abstract

This works employed K₂Ti₄O₉, a novel Ti source, to prepare TiO₂ powders. By a "low-temperature dissolution-reprecipitation process" (LTDRP), rutile phase TiO₂ was successfully synthesized after reacting at 50 °C for 48 h. The obtained sample showed a specific surface area about 45 m²/g, and excellent activity in photo-destruction of NO_x gas. The coupling of rutile phase TiO₂ with commercial anatase TiO₂ showed significant effect in further enhancing the photocatalytic activity.
