Description

An investigation was made of high-performance photocatalyst synthesis by low-temperature heating of amorphous TiO2 treated with hydroxyl peroxide. Peroxo titanic acid seems to be formed after the reaction of amorphous TiO2 with hydroxyl peroxide. The high-performance photocatalyst is fabricated by heat treatment with peroxo titanic acid at lower temperature (for instance 100°C). The TiO2 photocatalyst was applied to the removal of acetaldehyde in the air with results better than those obtained with commercial P-25 TiO2.
