| Abstract: | TiO 2, ZnO and Fe 2O 3 ultrafine particles were prepared. The structures and the particle sizes of the ultrafine particles were characterized by means of XRD. The photocatalytic oxidation of heptane was used to measure the photocatalytic activity of the usual and the ultrafine particles, which have defferent particle sizes. The order of the photocatalytic activity is TiO 2(A)> ZnO>Fe 2O 3. The potocatalytic activity of anatase TiO 2 is higher than that of rutile TiO 2. For the particles with the same type of structure. The smaller the particle, the higher the photocatalytic activity. |
