The „active” titanium dioxide consists of nanoscale particles in the „anatas” form. On nano particles the surface properties dominate compared to the volume properies that determine the characteristics of „normal” substances. The surface properties result amongst other things in the photocatalytic effect of the nano titanium dioxide.
