Abstract

The invention provides a monodisperse flower-like spherical MoS 2 A powder and a preparation method thereof, the method comprising the following steps: uniformly dispersing molybdate and thiocyanate in an ionic liquid composed of imidazolium cations and halogen anions, and then uniformly mixing with hydrochloric acid solution, controlling the pH to be 1.7-1.1 , to obtain a mixed system B; put the mixed system B in a closed container, react at 220 ° C for 24 hours, and obtain a black product after cooling; wash the black product with water and an organic solvent and dry to obtain a monodisperse flower-like spherical MoS 2 Powder. The method of the present invention uses a hydrothermal method to prepare monodisperse spherical MoS in one step 2 , adding ionic liquids to the raw materials and controlling the pH value of the reaction system makes the operation easy to control and the preparation conditions easy to achieve; the preparation method is simple, the cost is low, and the monodisperse flower-like MoS is significantly improved 2 adsorption performance. Curd-shaped MoS prepared by the present invention 2 The powder has large adsorption capacity and excellent adsorption performance.

Description

technical field [0001] The invention belongs to the field of preparation and application of inorganic functional materials, in particular to a monodisperse flower-like spherical MoS 2 Powder and its preparation method. Background technique [0002] In contemporary times, dye pollution from different sources (such as textile industry, paper and pulp industry, dye industry, pharmaceutical industry, tanning industry and sulfate bleaching industry, etc.) has aroused widespread concern in society. The control of organic dye pollution has become an important task of environmental governance. As a functional material, molybdenum sulfide has been found to have photocatalytic properties, but the existing preparation methods of molybdenum sulfide are relatively harsh. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a monodisperse curd-like MoS 2 Preparation method of powder, preparation of monodi...
