Monatomic metal-doped few-layer molybdenum disulfide electrocatalytic material, preparing method thereof, and method for electrocatalytic nitrogen fixation

摘要

The present invention provides a monatomic metal-doped few-layer molybdenum disulfide electrocatalytic material, a preparing method thereof, and a method for electrocatalytic nitrogen fixation. The material has a few-layer ultra-thin and irregular flake-like microstructure with a length and a width of nanometer scale. A doping metal in the monatomic metal-doped few-layer molybdenum disulfide electrocatalytic material is dispersed in a form of single atoms. When the catalyst is used in electrochemical reduction of N₂, a Faradic efficiency in selective reduction of N₂ into NH₄⁺ is 18% or above, and stability of the catalyst is better.
