Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force. In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and

The photocatalytic performance of TiO 2 could also be improved via nitrogen-doping as it can narrow down the band gap and eventually enable the absorption of visible light. 156 In contrast to conventional sputtering (followed by calcination), N-doped TiO 2 can be readily attained by ball milling. 157-160 In its synthesis, TiO 2 (most commonly P25) is ball milled with a nitrogen source compound

One-step ball milling synthesis of VO 2 (M) nanoparticles Figure 1 a shows the XRD patterns of samples milled with different molar ratios of V 2 O 5 to activated carbon (2:0.5–2:8) for 1 h. The small diffraction peaks of VO 2 (M) (JCPDS no. 043-1051) appear when the molar ratio is 2:0.5, which suggests that V 2 O 5 can be effectively reduced to VO 2 by activated carbon during ball milling
