Abstract: The decomposition of MoS₃ prepared from different sulphur sources is a very convenient method to synthesize nano-MoS₃. It was found the sulphur sources had an obvious influence on the MoS₃ morphology and size. MoS₃ from CH₃CSNH₂ contained hollow nano-balls or solid nanoparticles, while that from Na₂S comprised microparticles. Heating the obtained MoS₃ hollow nano-balls and solid nanoparticles under H₂, respectively, led to ∼150 nm MoS₂ nano-balls and ∼40 nm MoS₂ nanoparticles. However, Calcining the micro-MoS₃ from Na₂S under H₂ produced ∼30 nm MoS₂ nanoslices. The all obtained MoS₂ samples represented a typical layered structure.
