Abstract
Owing to its unique structure of mesoporous carbon shell and hollow tubular core, mesoporous carbon nanotubes (mCNT) are highly regarded as one of the most intrinsic adsorbing materials. Based on its significant property, a catalyst-free and shape-controllable reduction mechanism of ammonium metatungstate (AMT) in mCNT (AMT@mCNT) has been investigated. Reactions in mCNT are distinct because the mesoporous nanotubes can adsorb and release substances during the process. Using a field emission scanning electron microscope, X-ray diffraction, thermogravimetry and mass-spectrometric, the mechanism is determined. Finally, referring to the mechanism, tungsten nanowires and nanodots have undergone shape-controllable preparation via reduction of AMT@mCNT.
