Sn, Pb, Ag, and Au are encapsulated within carbon nanotubes (CNTs) by capillary action. From high‐resolution transmission electron microscopy imaging of the obtained materials, it is found that although Ag and Au crystallize within CNTs, Sn and Pb are in a pseudoliquid phase. The results suggest that a confined nanospace prevents crystal growth of metals having a low melting point.
