Rhenium sulfide nanotube, and preparation method and application thereof

Abstract

The invention provides a preparation method of the rhenium sulfide nanotube. The preparation method comprises the following steps: mixing a rhenium precursor and a sulfur precursor in deionized waterto obtain a first mixture solution; adding aqueous phase colloid of tellurium nanowires into the mixture solution to obtain a mixed suspension; sealing the mixed suspension, carrying out treatment ina high-temperature environment, cooling to room temperature, and collecting to obtain black powder; and cleaning and drying black powder to obtain rhenium sulfide nanotube. The rhenium sulfide nanotube provided by the invention has the advantages of simple preparation process and lower cost, and is suitable for large-scale industrial production.

Problems solved by technology

[0003] At present, the synthesis method of rhenium disulfide nanosheets has the following reports: T.Fujita et al. in the literature titled "Chemically exfoliated ReS2 nanosheets" ("ReS2 prepared by chemical exfoliation method Nanosheets") were prepared by chemical exfoliation technology rhenium disulfide nanosheets, this method needs to be carried out in an inert gas protection environment, and the lithium compound used is flammable in the air, which brings inconvenience and danger to the operation

N.Al-Dulaimi etc. in the literature titled "Sequential bottom-up and top-down processing for the synthesis of transitionmetal dichalcogenide nanosheets: the case of rhenium disulfide (ReS2)" ("Sequential bottom-up and top-down processing In the synthesis of transition metal disulfide precursor nanosheets: the case of rhenium disulfide (ReS2), two techniques, spray-assisted chemical vapor deposition and liquid phase exfoliation, were used to prepare rhenium disulfide nanolayers. This method requires two steps Operation, spray-assisted chemical vapor deposition requires high temperature and cumbersome process

In the literature titled "Vertically Oriented Arrays of ReS2Nanosheets for Electrochemical Energy Storage and Electrocatalysis", J.Gao et al. used chemical vapor deposition technology to prepare vertical Oriented rhenium disulfide nanosheets, the process requires complex control conditions and high reaction temperature

Therefore, there are still huge challenges in the low-cost, large-scale preparation of rhenium disulfide nanosheets.
