Ammonia, as one of the most important industrial chemicals, plays an irreplaceable role in the fields of pesticides, chemical fertilizers, textiles and the like. However, the production of ammonia is a difficult problem troubling the world all the time. The traditional Hobblog method is still adopted in the industry at present, the reaction can only be carried out under the conditions of high temperature and high pressure, and a large amount of fossil raw materials are wasted and the environment is seriously polluted. Scientific researchers find a method for reducing nitrogen into ammonia gas under an environmental condition. The electro-catalytic nitrogen reduction reaction can reduce N2 into NH3 under an external voltage under the environmental condition, the reaction condition is mild, carbon emission is less, and raw materials are easy to obtain, so that more and more attention is gained in recent years. Due to the strong dipole moment of N=N, nitrogen adsorption and serious hydrogen evolution reaction, electro-catalytic nitrogen reduction still faces many difficulties. Therefore, development of a high-activity and high-selectivity electrochemical catalyst is the key of electro-catalytic nitrogen reduction. The invention provides a preparation method for loading Fe3O4 on MoS2 nanoflowers through a hydrothermal method and application of the obtained catalyst to electro-catalytic nitrogen reduction.
