Enhancing Ammonia Synthesis Catalysts: Unraveling the Role and Development of Additives

In the realm of ammonia synthesis, catalysts vary, encompassing iron-based, ruthenium-based, molybdenum-based, rhodium-based, nickel-based, and silver-based catalysts. Each type presents unique advantages and drawbacks. Iron-based catalysts, notably cost-effective with high catalytic activity, dominate the landscape of thermochemical ammonia synthesis. However, their susceptibility to high-temperature decomposition necessitates regular replacement.
Challenges and Solutions: Iron-Based Ammonia Catalysts

The introduction of additives serves as a common solution, aiming to overcome challenges such as high-temperature decomposition and limited selectivity. These additives, including aluminum oxide (Al2O3), magnesium oxide (MgO), potassium oxide (K2O), calcium oxide (CaO), and silicon dioxide (SiO2), play a crucial role in enhancing iron-based ammonia catalysts.
Functionality of Catalyst Additives: A Multifaceted Approach

Each catalyst additive contributes uniquely, influencing surface area, stability, and chemical composition. For instance, aluminum oxide (Al2O3) prevents iron fine crystal growth, enhancing activity. However, its addition may slow down the catalyst's reduction rate. Ongoing research, exemplified by Sun Zhenzhen's work, explores optimal auxiliary catalysts for Fe1-xO-based ammonia synthesis.

Research Highlights: Optimal Auxiliary Catalysts

Chen Ping's exploration at the Dalian Institute of Chemical Physics emphasizes the pivotal role of alkali (earth) metals in green ammonia synthesis. Recent studies reveal the potential application of alkali (earth) metals, such as Ca-based molecular complexes, in homogeneous nitrogen fixation, showcasing their multifunctional properties.
