摘要: Abstract The closed layered MoS 2 nano-balls and the opened nano-slices were prepared by decomposing 3 in hydrogen atmosphere. obtained nanoparticles respectively used as catalysts for S 2− oxidation into SO 4 lubricating fillers polyoxymethylene (POM) plastic. Only basal surface could be found nano-balls, which represented very low catalytic efficiency . However, of both rim-edge showed excellent properties. Moreover, it was shown that improve self-lubrication POM plastic vacuum. led to obvious degradation POM, implying is not a proper additive POM. high activity catalyzing degrading ascribed their small sizes partly wedge-like shapes, considerable increase rim sites. weak catalysis lubrication resulted from its structure chemical inertness.
