摘      要：Chain-like MoS2assemblies consisting of hexagonal MoS2nanoparticles(20-60 nm) have been successfully synthesized in a Triton X-100/cyclohexane/hexanol/water W/O reverse microemulsion in the presence of(NH 4)2MoS 4 as the molybdenum source and NH2OH·HCl as the reducing *** products were characterized by X-ray powder diffraction(XRD),transmission electron microscopy(TEM) and UV-vis diffuse reflectance absorption *** influence of synthetic parameters such as acidity,water/oil ratio(0),aging time and annealing temperature on the formation of MoS2assemblies was *** analysis showed that these synthetic factors played important roles in controlling the size of MoS2nanoparticles and the length of the chain-like *** analysis indicated that the well-crystallized MoS2nanoparticles could be obtained by annealing the precursors at 700 C for2h under a flow of *** addition,the as-prepared chain-like MoS2nanoparticles exhibited excellent photocatalytic H2activity in Ru(bpy) 3 2+-MoS2-H2A three-component molecular systems under visible light irradiation.
