Abstract

Nb-doped WS2 nanotubes, typically W1-xNbxS2(x≤0.2), generated by heating Nb2O5-coated W18O49 nanorods in H2S at 1100°C, contain more structural defects within the layers than do pure WS2 nanotubes. The tube tips are invariably closed. The presence of Nb appears to inhibit nanotube formation. A two-stage process is proposed to account for the observed doped nanotube growth.
