Mechanical Milling: a Top Down Approach for the Synthesis

Feb 03,  · The formation of coiled nanotubes and nanofibres were observed in the BMC sample. The BMC samples with and without nickel (Ni) catalyst were subjected to hydrogenation cycling also. The vibratory ball mill was used to decrease the single-wall carbon nanotubes length and to increase their specific surface area by N. Pierard et al[99].

High energy ball milling process for nanomaterial synthesis

Besides materials synthesis, high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions during milling (mechanochemistry).
