| Abstract | The closed layered MoS2 nano-balls and the opened layered MoS2 nano-slices were prepared bydecomposingMoS3 in hydrogen atmosphere. The obtainedMoS2 nanoparticleswere respectively used ascatalysts for S2 oxidation into SO42 and lubricating fillers in polyoxymethylene (POM) plastic. Onlybasal surface could be found in the closed layeredMoS2 nano-balls,which represented very lowcatalyticefficiency for S2 oxidation into SO42 . However, the opened layeredMoS2 nano-sliceswere of both basalsurface and rim-edge surface and showed excellent catalytic properties. Moreover, it was shown thatMoS2 nano-balls could improve the self-lubrication of POM plastic in vacuum. However, MoS2 nano-slices led to the obvious degradation of POM, implying it is not a proper additive for POM. The highactivity of MoS2 nano-slices for catalyzing S2 oxidation and degrading POM was ascribed to their smallsizes and partly wedge-like shapes, which led to a considerable increase in the rim sites. The weakcatalysis and excellent lubrication of MoS2 nano-balls were resulted from its closed structure andchemical inertness. |
