Abstract
Chain-like MoS2 assemblies consisting of hexagonal MoS2 nanoparticles (20-60 nm) have been successfully synthesized in a Triton X-100/cyclohexane/hexanol/water W/O reverse microemulsion in the presence of (NH4)(2)MoS4 as the molybdenum source and NH2OH center dot HCl as the reducing agent. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and UV-vis diffuse reflectance absorption spectra. The influence of synthetic parameters such as acidity, water/oil ratio (omega(0)), aging time and annealing temperature on the formation of MoS2 assemblies was investigated. TEM analysis showed that these synthetic factors played important roles in controlling the size of MoS2 nanoparticles and the length of the chain-like MoS2 assemblies. XRD analysis indicated that the well-crystallized MoS2 nanoparticles could be obtained by annealing the precursors at 700A degrees C for 2 h under a flow of N-2 atmosphere. In addition, the as-prepared chain-like MoS2 nanoparticles exhibited excellent photocatalytic H-2 activity in Ru(bpy) (3) (2+) -MoS2-H(2)A three-component molecular systems under visible light irradiation.
