Abstract

Nb-doped WS₂ nanotubes, typically W_1-xNb_xS₂(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.
