FeS nanosheet preparing method

Abstract

The invention discloses a FeS nanosheet preparing method. The method comprises the steps of 1, dissolving an iron-containing precursor, a sulfur-containing precursor and a surface active agent in water to obtain a solution, wherein the surface active agent is hexadecyl trimethyl ammonium bromide; 2, transferring the solution obtained in the step 1 into a reaction still to be heated, conducting centrifugation after complete reaction, washing a sample with water and ethyl alcohol, and then obtaining a FeS nanosheet. According to the method, the technology is simple, production cost is low, and the prepared FeS nanosheets have a uniform shape and a thickness of about 3 nm and are suitable for directly preparing a lithium battery electrode material; during preparation, water serves as the solvent, preparation is safe, cost is low, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a preparation method of FeS nanosheets. Background technique [0002] FeS, also known as pyrrhotite, has a scaly structure similar to molybdenum disulfide and graphene. It is a diamagnetic semiconductor material and has been widely used as a solid lubricant, lithium battery electrode material, etc. [0003] The preparation of ultrathin semiconductor nanosheets by solution method is one of the most important research frontiers in material science, and a lot of research has been done at home and abroad. However, most of the methods currently used are oil-phase methods, so a lot of toxic organic solvents are often used. [0004] The hydrothermal method, as a method using water as the reaction medium, is applied to the synthesis of various inorganic semiconductor nanomaterials, which has the advantages of high safety, but so far, there is no literature on the synthesis of ult...
