TiO 2 nanopowders, doped with Fe 3+ and Eu 3+ were obtained by high-energy ball milling and their physical properties were investigated as a function of the doping content and ball milling time. A noticeable red shift and high photoactivity in the degradation and catalytic oxidation reactions of styrene and phenol were found for all doped specimens.
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 (Ti, 15W, 5Mo, 0.2V)(CN)-20Ni composite powders were prepared by oxides via tumbling ball milling and high-energy ball milling and subsequent carbothermal reduction nitridation.
Hybrid CuxO–TiO2 Nanopowders Prepared by Ball Milling for Solar Energy Conversion and Visible-Light-Induced Wastewater Treatment ACS Applied Nano Materials. Hybrid nanocomposites of Cu2O–(R)TiO2, CuO–(R)TiO2, and Cu3TiO4–(R)TiO2 (where R represents the rutile phase of TiO2) nanopowders (NPs) were produced via solid state reaction followed by 20 h
Abstract. αFe 2 O 3 /TiO 2 Composite powders have been prepared by high energy ball-milling for different times. The composites were studied using Möss Spectroscopy (MS) and X-ray diffraction (XRD).
Buoyant carbon and nitrogen co-doped TiO 2 /polytetrafluoroethylene (NCT/PTFE) flakes which meet these requirements were prepared by the high-energy ball-milling of NCT powder and PTFE. The physicochemical properties of the as-prepared composite flakes were evaluated by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet–visible diffuse reflection spectroscopy (UV-vis

In our opinion, using micro-sized TiO 2 as starting materials is an efficient way to reduce the preparation cost of Li 4 Ti 5 O 12. After activated by high-energy ball milling, micro-sized TiO 2 has lower degree of crystallinity and smaller particle size, which is beneficial for the synthesis of Li 4 Ti 5 O 12.
