Tokyo researchers create stable barium catalyst for low-temperature ammonia synthesis
Scientists at the Institute of Science Tokyo in Japan have developed a new barium-based catalyst that enables ammonia production at lower temperatures.
Current limitations in ammonia production
Standard ammonia synthesis requires high heat and pressure because breaking nitrogen bonds consumes significant energy. Existing catalysts often use scarce noble metals like ruthenium or degrade when exposed to hydrogen.
New stable barium structure
The team designed a hierarchically structured material that protects the active barium subnitride core from degradation. This shell allows the catalyst to activate nitrogen molecules efficiently under milder conditions.
Study publication details
Dr Yihao Jiang and colleagues published their findings in the Journal of the American Chemical Society. The research offers a cost-effective alternative for sustainable fuel storage and transport.
