FESEM imaging scheme of how the tungsten carbide precursors are formed, showing (a) the original TNC-HMC/MS, (b) the BET/BJH result of TNC-HMC/MS, (c) controllably encapsulated AMT, (d) the corresponding back scattering image of panel (c), (e) the TEM image of mesoporous in the shell, (f) and (h) encapsulated AMT reduced in lower H flow rate which results in nanorod precursor, (g) the back scattering image of panels (h), (i) and (j) encapsulated AMT reduced in higher H flow rate which results in nanodot precursor.
