    S. Indris et al [91] prepared nanocrystalline powders of the anatase TiO 2 as well as the rutile TiO 2 modification by high-energy ball milling of the coarse grained source materials for 4 h. The average grain size was varied via the milling time in the range from some micrometers down to about 20 nm. They showed that the catalytic activity of TiO
