摘要：

Cold spray was employed as a novel low temperature approach to deposit titanium dioxide (TiO2) photocatalytic film. The film microstructure was characterized using X-ray diffraction and scanning electron microscopy. The photocatalytic performance was examined through acetaldehyde degradation under ultraviolet illumination. Results showed that TiO2 film was successfully deposited on substrate surface through cold spray. The film thickness reached up to 15 mm. The film presented a rough surface and porous structure. Owing to the low temperature of spray powder, no phase and particle size changes occurred to TiO2 during deposition. It was found that the cold-sprayed TiO2 film was active for photodegradation of acetaldehyde. (C) 2007 Elsevier B.V. All rights reserved.
