Description

technical field

[0001] The invention relates to the field of electrocatalysts for electrochemical synthesis of ammonia, in particular to a MoS 2 / S-NiCoCr-LDH composite material preparation method. Background technique

[0002] Ammonia is an important chemical production raw material and chemical product. The output of ammonia is the largest among all chemical products in the world, because it is indispensable in the manufacture of nitrogen fertilizer and the production of various compound fertilizers. One of the missing raw materials. Therefore, it can be said that ammonia has played a fundamental role in the advancement and prosperity of human economy and civilization. In addition, the proportion of hydrogen in ammonia molecules is also very high, which can reach 17.6%. Compared with liquid hydrogen, liquid ammonia has the advantages of safety, stability and ease of transportation, so it can be used as a medium for storing energy and hydrogen. Modern ammonia synthesis t...
