Synthesis and Characterization of Hierarchical Structured

Mar 19, 2015 Due to the high surface energy introduced by ball milling process, hierarchical TiO 2 nanotubes could absorb more reaction substrate, which results in a faster degradation in the initial tens of minutes. The degradation rate of P25 went faster in the last several minutes because of the influence of the anatase-rutile mixed phase.

High energy ball milling process for nanomaterial synthesis

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. However, using optimized milling speed and milling time
