AI Technical Summary
Technical Problem
Existing ammonia synthesis catalysts, such as those used in the Haber-Bosch method, are difficult to handle and require high temperatures and pressures, while alternative catalysts like ruthenium-based systems are sensitive to atmospheric deactivation.
Method used
A catalyst comprising iron and aluminum hydride, obtained by heat-treating a mixture of iron oxide and aluminum salt in a nitrogen and hydrogen atmosphere, which is easier to handle and exhibits high catalytic activity at lower temperatures.
Benefits of technology
The catalyst achieves high ammonia production rates at temperatures below 50°C, with improved stability and handling characteristics compared to traditional systems, and maintains activity even at low temperatures and pressures.
