“…For a planetary ball mill, the high dynamic energies, which are generated by the difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, resulting in its higher grinding efficiency and ability to produce finer particles. Therefore, planetary ball mills have often been used for the preparation of BM-CNMs recently …”

“…Therefore, planetary ball mills have often been used for the preparation of BM-CNMs recently. 67 To reduce chemical degradations (e.g., oxidation) and physical fragmentation/destruction of CNMs during the ball-milling process, an inert gas such as argon (Ar), NH 3 , or C 2 H 4 is often used to fill in the milling chambers for BM-CNM preparation. 68−70 Chen et al 71 have developed an approach to prepare curved or closed-shell carbon nanostructures by ball milling of graphite in a dry pure Ar atmosphere.…”

With exceptional physicochemical properties, carbon nanomaterials (CNMs) have been widely applied in various energy and environmental applications including energy conversion, energy storage, and environmental remediation. Recent efforts have been made to prepare modified CNMs with improved electrical and chemical properties, hence broadening their potential applications. It is highly desirable to produce high-quality CNMs at a low cost and large scale, which remains a challenging task. Ball-milled CNMs (BM-CNMs) are a novel class of engineered materials that may provide new opportunities to satisfy the need. To promote the research on BM-CNMs, this work provides a comprehensive review on recent research development in (1) synthesis of various types of BM-CNMs, (2) effects of ball milling on physicochemical properties of BM-CNMs, and (3) energy and environmental applications of BM-CNMs. Different ball-milling processes for preparing BM-CNMs and modified BM-CNMs with desired particle size, structure, and surface properties are summarized and discussed. The physicochemical properties of pristine CNMs and BM-CNMs are compared. Because of BM-CNM’s unique properties, such as excellent catalytic, electrochemical, and sorptive properties, their potential applications in energy conversion, energy storage, and environmental remediation are also discussed. Key challenges and further research needs are proposed at the end.

“…3c and d). 23,24 Using the model developed by Abdellaoui and Gaffet, 25,26 we estimated the kinetic energy provided by the planetary centrifugal mixing using sub-micrometer scale LO powder as the ball milling agent, to be in the order of 7.7 Â 10 À16 J per collision compared to 3.8 Â 10 À6 J per collision using a 10 mm (diameter) ZrO 2 grinding agent. This less impactful but much better distributed energy (proportional to the number of particles) led to the homogeneous mixture with undamaged oxidized CNTs.…”
