The ball mill machine was then operated at a speed of 300 rpm for 12 h and the rotation direction altered every 3 h. The resultant ball-milled biochars were labeled with BM, namely, BMHC450, BMHC600, BMBG450, and BMBG600. The N-doped biochar was prepared by ball milling 1.8 g biochar samples with 18 mL ammonium hydroxide (29%).

Commercially available ball mills do not have strict temperature control, limiting the information that can be obtained to inform the scale-up process reliably. This work uses an in-house modified, temperature-controlled, ball mill to bridge the knowledge gap regarding predictable, well-informed, economical, and reliable mechanochemical scale-ups.

SEM analysis confirmed the surface morphologies of ball-milled biochar and H 2 O 2-modified biochar (Figure S1, Supplementary Material).Ball milling crushes the granular pristine biochar into ultra-fine particles and form porous and rough surface (Lyu et al., 2018a).The effect of H 2 O 2 treatment was to oxidize the ball-milled particles, resulting a smooth surface and a flat structure.
