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