One-step ball milling synthesis of VO2 (M) nanoparticles

2021-3-8  2021-3-8  One-step ball milling synthesis of VO 2 (M) nanoparticles. Figure 1a 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
