Abstract

The invention provides a preparation method for a high-purity tin diselenide nanometer piece, and relates to the technical field of hydrothermal chemical synthesis nanometer material process. According to the invention, three solid powders of SnCL2.2H2O, SeO2 and NaOH, hydrazine, and ammonia water are adopted to prepare the tin diselenide nanometer piece through the steps of reaction, heating, washing, drying and the like. The obtained tin diselenide has high purity, good dispersibility, and a regular and even shape. The technical process is safe; and the auxiliary solution and products of the process can be easily treated without pollution. Therefore, the method has broad application prospects.

Description

technical field

[0001] The invention relates to the technical field of hydrothermal chemical synthesis of nanomaterials, in particular to a preparation method for synthesizing tin diselenide nanosheets by hydrothermal method. Background technique

[0002] Nanomaterials refer to materials that have at least one dimension in the three-dimensional space in the nanoscale range of 1-100nm or are composed of them as basic units. Nanomaterials have raised many new topics for condensed matter physics. Due to the small size of nanomaterials, the quantum size effect is very significant, which makes the optical, thermal, electrical, magnetic and other physical properties of nanomaterial systems different from conventional materials, and many novel properties appear. ; Another important feature of nanomaterials is the surface effect. As the size decreases, the specific surface area increases greatly, resulting in a large difference between the chemical properties of the nanosystem and ...
