Abstract
Hollow fibres of crystalline W18O49, arranged in a pine-tree-like structure , were generated by heating WS2 powder in oxygen. SEM, TEM, X-ray and elect ron diffraction studies show that the individual fibres are composed of sin gle-crystal tungsten oxide whiskers. One-dimensional growth, involving heat dissipation along the fibre axis, is proposed.
