Ball milling of graphite with appropriate stabilizers is another mode of exfoliation in liquid phase. 21 Graphite is ground under high sheer rates with millimetersized metal balls causing exfoliation to graphene (Fig. ), under wet or dry instance, this method can be employed to produce nearly 50 g of graphene in the absence of any oxidant. 22 Graphite (50 g) was ground in
#0183;#32;This is a first systematic report on the synthesis of completely nanocrystalline metals by highenergy deformation processes. Pure metals with bodycentered cubic (bcc) and hexagonal closepacked (hcp) structures are subjected to ball milling, resulting in a decrease of the average grain size to 9 nm for metals with bcc and to 13 nm for metals with hcp crystal structures.
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 of ball milling; their photocatalytic activities were evaluated for methylene blue () degradation under visible light intensity (65 mW/cm2) and compared to Degussa P25 under both ultraviolet
Cu/SAPO34 catalysts were prepared by different solidstate ion exchange methods,, mechanical mixing (Cu/SAPO34M) and ball milling (Cu/SAPO34B), and were used for selective catalytic reduction of NO x with NH 3 (NH 3SCR) with Cu/SAPO34M, Cu/SAPO34B exhibited more excellent NH 3SCR catalytic characterization methods, including
A novel NiFe bimetal with high dechlorination activity for 4chlorophenol (4CP) was prepared by ball milling (BM) in this study. Increasing Ni content and milling time greatly enhanced the dechlorination activity, which was mainly attributed to the homogeneous distribution of Ni nanoparticles (50100 nm) in bulk Fe visualized by scanning electron microscopy/energy dispersive Xray
For all nanocrystalline materials prepared by highenergy 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 highenergy ball milling.
