Abstract

The invention relates to a synthesizing method for a transition metal sulfide, which comprises the following steps: 1) dissolving cobalt salt or copper salt which can be dissolved in ethanol in ethanol, then adding CS2; 2) transferring the obtain solution to an autoclave for conducting heated and constant-temperature reaction to produce transition metal sulfide powder; and 3) sequentially filtering, washing and vacuum-drying the produced transition metal sulfide powder to obtain the finished product, wherein the cobalt salt or copper salt which can be dissolved in ethanol is sulfate, chlorate, nitrate or acetate. The invention has the advantages that the cost of raw materials is low, the production technology is simple, the reaction conditions can be easily controlled, the template agent and the surfactant are not required, the uniformity of the obtained product is good, the environment-friendliness is high and the mass production of the transition metal sulfide is facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of material synthesis, in particular to a synthesis method of transition metal sulfides. 【Background technique】 [0002] In recent years, transition metal sulfides have attracted extensive research interest due to their excellent optical, electrical, magnetic, lubricating, and catalytic properties, and have been successfully applied in various fields, such as industrial catalysts, lithium-ion batteries, and alkaline Negative electrode materials for permanent secondary batteries, semiconductor materials, optoelectronic materials, etc. Transition metal sulfides are also used in the field of environmental protection and play an important role in the removal of heavy metals. [0003] The traditional synthesis techniques of transition metal sulfides mostly involve multiphase reactions under high-energy and inert gas protection, usually using high-temperature gas-phase or high-temperature solid-phase synthesis,...
