T. Tsirlina et al., SYNTHESIS AND CHARACTERIZATION OF INORGANIC FULLERENE-LIKE WSE2 MATERIAL, Fullerene science and technology, 6(1), 1998, pp. 157-165
Lately MoS2 and WS2 fullerene-like nanoparticles, generically termed i
norganic fullerene-like (IF) materials, were reproducibly obtained by
gas phase(4,6) and solid state(6) reactions and the growth mechanism o
f such structures was elucidated(6). The present work deals with the s
ynthesis of IF-WSe2 from tungsten oxide and selenium vapors. Thermodyn
amic calculations of the sulfidization and selenization processes are
provided, and indicate salient differences between the two processes.
Notwithstanding, the growth model of IF-WSe2 is similar to that of sul
fide fullerene-like material. The IF-WSe2 was characterized by X-ray p
owder diffraction, transmission electron microscopy and high resolutio
n transmission electron microscopy.
