Dec 25, 2011 TiO 2 nanoparticles were synthesized by a sol–gel method and the effect of ball milling of dried gel on the particle size has been investigated. The results show that the ball milling has a crucial role in preparation of nanosized TiO 2 powder. Also thermal treatment at different temperatures can control the size of prepared nanoparticles.

For all nanocrystalline materials prepared by high-energy ball milling synthesis route, surface and interface contamination is a major concern. In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2 , N 2 in rare gases) can be problems for high-energy ball milling.
Herein, we report an inexpensive method for mass-scale production of TiO 2 ETMs at room temperature (RT ∼ 30 °C), involving the grinding of large clumps of an-TiO 2 to form a suspension of TiO 2 nanoparticles (NPs) in isopropyl alcohol for meso-superstructured PSCs. This process does not involve any chemical synthesis; it is a purely ...

Whereas the ball-milling time (Figure 1a) and agate ball-to-CuO mass ratio (Figure 1b) had little effect on RR120 adsorption onto CuO, the milling speed (Figure 1c) showed greater influences. The highest RR120 adsorption capacities under different ball-milling conditions were 65.38, 66.54, and 63.56 mg g−1at a milling time of 9 h,

Jul 22, 2014 In this research work, TiO 2 nanoparticles were doped with iron powder in a planetary ball-milling system using stainless steel balls. The correlation between milling rotation speeds with structural and morphologic characteristics, optical and magnetic properties, and photocatalytic abilities of bare and Fe-doped TiO 2 powders was studied and ...
Feb 03, 2012 By adopting TiO 2 /C composite as the reactant, the formation of Li 4 Ti 5 O 12 phase was more likely to happen by calcination in N 2 than in 10% H 2-Ar due to the suppressing effect hydrogen for the decomposition of Li 2 CO 3 to Li 2 O. Li 2 O/CuO nanocomposites were prepared by ball-milling of the CuO and Li 2 O nanoparticles with rigid TiN ...
TiO 2 nanoparticles were prepared by the use of high energy ball milling of titanyl sulphate (TiOSO 4) and NaCl powders as the starting mixture in different milling durations. The milled powder was annealed at 700°C for 30 min.

The structural transformation of anatase TiO 2 by high-energy vibrational ball milling was studied in detail by different analytical methods of x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). This structural transformation involves both phase transition and nanoparticle formation, and no amorphization was observed.
