Problems solved by technology

However, molybdenum disulfide with a high specific area tends to agglomerate with each other, thereby reducing its effective contact area with the electrolyte, resulting in a greatly reduced electrocatalytic effect.
In addition, molybdenum disulfide is a semiconductor material. Although the 1T phase molybdenum disulfide has metallic properties, the improvement in conductivity is limited. If the 1T phase molybdenum disulfide is directly used as an electrocatalytic material, it is not conducive to the effective transmission of electrons.

Description

technical field [0001] The invention relates to the technical field of molybdenum disulfide / carbon fiber cloth nanocomposite materials, in particular to a method for synthesizing 1T phase molybdenum disulfide / carbon fiber cloth nanocomposite materials by a hydrothermal method. Background technique [0002] As a representative of two-dimensional layered transition metal sulfides, molybdenum disulfide has attracted widespread attention in many fields due to its special atomic structure, large specific surface area, and excellent chemical and thermal stability. Molybdenum disulfide has three atomic layers, and the layers are stacked by weak van der Waals force. Therefore, it is easy to peel off between layers to form a molybdenum disulfide monolithic layer structure, thereby increasing the contact area of ​​the electrode and improving the structural characteristics. There are three common crystal structures of molybdenum disulfide: 1T, 2H, and 3R phases. 2H and 3R phase molyb...
