| Abstract: | The photocatalytic Oxidation of HCHO was used as a model reaction to investigate the photocatalytic properties of different commercial TiO 2 catalysts. Parallel experiments have been performed with a black_light lamp in a close photoreactor in laboratory.Different photocatalyst activities were observed. The results showed that Degussa P25 presented a higher activity for HCHO disapperance than the other commercial catalysts because of its greater surface area and crystal structure. The factors that influence photocatalytic activity of the catalysts were discussed. |
| Keywords: | photocatalysis commercial titanium dioxide HCHO |
