Abstract
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.
