Реферат:
Although many of the layered metal chalcogenides, such as MoS2, are well-studied, some other chalcogenides have received less attention by comparison. In particular, there has been an emerging interest in vanadium tetrasulfide (VS4), which displays useful properties as a component of hybrids. However, the synthetic methods and characteristics of individual VS4are not yet well defined, and there is no report on its solution processability. Here we have synthesized VS4by a simple and fast direct reaction between elements. Reinvestigation of the VS4crystal structure yielded more precise atomic coordinates and interatomic distances, thereby confirming the crystallization of VS4in the monoclinic C2/c group and its quasi-1D chainlike structure. As the chains in VS4are only bonded by weak van der Waals forces, we further demonstrate that bulk VS4may be ultrasonically dispersed in appropriate solvents to form colloids, similarly to the layered chalcogenides. VS4particles in colloids retain their phase identity and rod-shaped morphology with lengths in the range of hundreds of nanometers. Isopropanol dispersion exhibited the highest concentration and stability, which was achieved owing to the repulsion caused by high negative charges on the edges of the particles. © 2015 Wiley-VCH Verlag GmbH & Co.
