Figure 3. Growth rate of Mo2C within and between MoO2 NPs. (A-J) In-situ TEM images of structural evolution from stacked MoO2 NPs to Mo2C under 20 vol.% CH4/H2 atmosphere at 700 °C; (K) The carbonization rates within and between MoO2 NPs. The boxes represent the growth rate of two-dimensional area of porous Mo2C. Blue numbers represent the number of interfaces with Mo2C growth crossing between MoO2 NPs, and the capital letters represent the corresponding TEM images in (B-J). NPs: Nanoparticles; TEM: transmission electron microscopy.
