“…Therefore, materials with the self-assembly of complex nanostructures have drawn a large number of researchers' widespread attention on multiple areas because of their special properties and great potential applications in future compared with bulk materials. Accordingly, various morphologies of MoS 2 were successfully prepared, such as nanowires [11], nanotubes [12], nanorods [13], the hollow microspheres [14], nanoflower [15] and nanopolyhedron [16].…”

In this paper, flower-like MoS 2 nanosheets microspheres were successfully synthesized by low temperature hydrothermal process using the precursors of sodium molybdate (Na 2 MoO 4 Á2H 2 O), thiourea (SC(NH 2 ) 2 ), oxalic acid (C 2 H 2 O 4 Á2H 2 O) and de-ionized water. The effects of oxalic acid concentrations and growth time on the morphology and crystallographic structure of MoS 2 nanosheets microspheres were investigated. The morphology, crystallographic structure, chemical composition of the flower-like MoS 2 nanosheets microspheres were investigated by using scanning electron microscope, X-ray diffraction, Raman spectrum, high resolution transmission electron-microscopy, and X-ray photoelectron spectroscopy, respectively. It is revealed that MoS 2 powders are composed of large, uniform flower-like microspheres, which are formed by several nanosheets gathering together perpendicular to the spherical surface. And the nanosheets are poly-crystallized hexagonal phase. The experiment results also show that the oxalic acid concentration in the precursors plays a key role on the diameter and crystalline of MoS 2 nanosheets microspheres. The formation mechanism of flower-like MoS 2 nanosheets microspheres was discussed.

Bulk-to-single layer molybdenum disulfide (MoS 2 ) is widely used as a robust candidate for photodegradation of organic pollutants, hydrogen production, and CO 2 reduction. This material features active edge sites and narrow band gap features, which are useful for generating reactive species in aqueous suspensions. However, the high-charge carrier recombination, photocorrosion, unstable sulfide state, and formation of Mo-S-O links during photocatalytic reactions limit its applicability. Thus, research has focused on improving the performance of MoS 2 by tailoring its bulk-to-single layer structure and combining it with other semiconductor materials to improve the photocatalytic performance. Different strategies have been successfully applied to enhance the photocatalytic activity of MoS 2 , including tailoring of the surface morphology, formation of heterojunctions with other semiconductors, doping, and modification with excess sulfur or carbon nanostructures. This review describes the influence of starting precursors, sulfur sources, and synthetic methods to obtain heterostructured morphologies and study their impact on the photocatalytic efficiency. Finally, the relevance of crystal facets and defects in photocatalysis is outlined. Future applications of MoS 2 with tailoring and tuning physicochemical properties are highlighted.

a b s t r a c tThe synthesis of MoS 2 nanoparticles from MoO 3 with a certain morphology through a surfactant-assisted hydrothermal process is described in this paper. MoO 3 , which has a nanobelt morphology with a width of 100-500 nm and a length from one to several micrometers, is used as the precursor, and poly(vinylpyrrolidone) (PVP) is used as the surfactant. The morphology of the resulting MoS 2 nanomaterial has been characterized by the field-emission scanning electron microscope, which shows that the obtained nanoparticles have diameters ranging from 50 to 100 nm with rough surfaces. Additionally, the composition and crystallinity as well as the phase information of the produced nanoparticles have been characterized by the energy-dispersive X-ray spectrometer and X-ray diffraction. Specifically, in this process, the presence of PVP plays a crucial role for the successful fabrication of the nanoparticle morphology, which may be due to the formation of PVP micelles leading to an oriented aggregation of MoS 2 nuclei. In addition, comparative experiments have been conducted and the possible reaction mechanism is proposed.
