We carried out a rational design of catalyst supports by high-energy ball milling. Tailored mixtures of TiO 2 crystalline phases were obtained using rotational speed and milling time as variable parameters. Polymorphic transformation from anatase to rutile through high-pressure TiO 2 (II) as intermediate was confirmed by X-ray Diffraction (XRD), Raman Spectroscopy and Transmission …

Titanium Aluminide based composites with Al2O3 reinforcement can be produced via reaction of Al with TiO2. These composites are considered as low price materials for high temperature applications. In this research, the effect of ball milling on 3TiO2/7Al system was investigated. On the basis of obtained results, ball milling for 0 to 60 h does not lead to reduction of TiO2 by Al. but reduces ...

Results. Ball mill treated TiO 2 (B) particles of less than 1.0 μm with a fraction of anatase phase, compared to as-synthesized TiO 2 (B) particles with about 24 μm in average particle size, showed a significant improvement in the electrochemical properties. They showed a much improved stability in the charge–discharge cycles and irreversibility. They maintained about 98% of the initial ...

Titanium dioxide (TiO2) is widely used for applications in heterogeneous photocatalysis. We prepared nanocrystalline powders of the anatase as well as the rutile modification by high-energy ball milling of the coarse grained source materials for up to 4 h. The resulting average grain size was about 20 nm. The morphology of the powders was investigated with transmission electron microscopy, X ...
