Synthesis of cluster nanostructures

Abstract

Almost immediately after the appearance of interest in carbon nanotubes (CNTs), research on inorganic nanotubes appeared. In 1992, the first results were obtained showing that nanotubular and fullerene-like structures are formed not only by carbon. In particular, the nanoparticles of the compound WS2, being unstable in a flat form, spontaneously form a closed structure related to fullerenes and CNTs. Later, such particles were synthesized from MoS2. Non-carbon nanotubes (NNT) are most often two-component compounds (BN, WS2, MoS2, SiC, etc.). Thus, a huge number of different compounds belong to the family of two-dimensional and one-dimensional materials, whose research is the actual task of modern science. In this paper, the synthesis of nanostructures is investigated by the method of gas-phase deposition (CVD-method), implemented using a Nabertherm tube furnace. The object of study is MoS2. The physicochemical parameters of the obtained nanostructures were studied using a JEOL JSM-7800F scanning electron microscope, a Nikon Eclipse LV 100 optical microscope and a SOLVER NEXT atomic force microscope. As shown by the results of the study, the obtained samples contained both particles of a molybdenum monolayer and tubular objects. The parameters affecting the growth of nanostructures were also established.
