Preparation method and application of nanometer rod-shaped V3S4

Abstract

The invention provides a preparation method and application of a nanometer rod-shaped V3S4. The preparation method comprises the following steps of firstly, carrying out hydrothermal reaction of a vanadium source solution to obtain a vanadium oxide nanometer material, wherein the concentration of a vanadium source is 0.01-0.10mol / L; and finally, roasting the vanadium oxide nanometer material whose mole ratio of vanadium to sulfur is (1:8)-(1:12) and a sulfur source substance in a tubular atmosphere furnace, cooling the roasted sample, and washing, cooling and drying the sample to obtain the nanometer rod-shaped V3S4. The method process is simple and is easy to control, and the prepared V3S4 nanometer powder is uniform in chemical constitution, relatively high in purity and relatively high in crystallinity, and shows excellent performance when taken as a ferromagnetic material and an electrode material of a lithium / sodium ion battery. Meanwhile, by the method, a V3S4 structure is controlled by a two-step method, and the controllable preparation of the nanometer rod-shaped V3S4 is further achieved; and further, the raw material is low in cost and is available, the cost is low, the yield is high, subsequent processing is not needed, and the method is friendly to an environment and can be suitable for mass production.
