The photoactivities of ultrafine TiO2 nanoparticles in the anatase, rutile or mixed-phases were tested in the photocatalytic degradation of phenol. For TiO2 nanoparticles mainly in the anatase phase and mixed-phases, their photocatalytic activities increased significantly with the content of amorphous part decreased, the result bring new understanding and insight to photocatalytic activity of TiO2 nanoparticles. The completely crystallized rutile nanoparticles exhibited size effect in this photocatalytic reaction, the photocatalytic activity of rutile-type TiO2 nanoparticles in the size 7.2nm was much higher than that in the size 18.5nm or 40.8nm and comparable to that of anatase TiO2 nanoparticles.
