Large-scale and morphology-controlled synthesis of nano-sized molybdenum disulphide particles by different sulphur sources

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.
