| Abstract: | Nanometer TiO_2 powder with anatase structure has excellent photocatalytic performance. Anatase TiO_2 demonstrated a higher photo-activity than rutile TiO_2 did. Spray mainly conducted by anatase nanometer TiO_2 was experimented to degrade unusable organic substances. Here formaldehyde was selected as a kind of typical contamination, the photocatalytic degradation of formaldehyde with the spray was investigated. Experiment results show that the amount of formaldehyde, TiO_2 crystalline type, light source TiO_2 crystalline dimension all affect the photocatalytic process. |
