摘要：

The adsorption kinetics of thiophene on WS(2) nanoparticles with fullerene-like (onion-like) structure has been studied at ultra-high vacuum conditions by sample temperature ramping techniques. At low temperatures, thiophene adsorbs molecularly. The formation of H(2)S and alkanes is evident at greater temperatures on fully sulfided as well as reduced and oxidized WS(2) nanoparticles.
