A brief review of the research on rare earth-promoted ammonia synthesis catalysts

Hydrogen energy is regarded as the clean energy with the greatest development potential in the 21st century, but its large-scale use is restricted by problems such as storage difficulties and transportation risks. Ammonia is considered to be the most promising hydrogen carrier of the next generation due to its many advantages such as high hydrogen storage capacity and easy liquefaction under mild conditions. Hydrogen production with ammonia storage is the future development trend.

Industrial ammonia synthesis usually requires high temperature and high pressure, so developing catalysts that can work efficiently under mild conditions and developing low-energy and high-efficiency ammonia synthesis processes are the key to realizing the application of ammonia as an energy source. The unique electronic structure of rare earth elements gives them adjustable oxygen vacancies and the ability to store and release electrons. They can provide key sites to promote N₂ activation by forming new active interfaces with metals, thus giving full play to the advantages of rare earth materials in the ammonia synthesis reaction.

Rare earth compounds, with their unique electronic structure and properties, show excellent catalytic performance in the ammonia synthesis reaction. Many methods have been optimized to synthesize rare earth-promoted catalysts with unique structures, special sizes and morphologies, which has brought new directions for in-depth research on rare earth-based ammonia synthesis catalysts.
