The cobalt-based catalyst achieves ammonia synthesis rates of 13.7 μmol·gcat-1·h-1 under ambient conditions, indicating significant efficiency.
Using density functional theory, the study discovered a transient confinement effect that lowers the energy barrier from 1.3 eV to 0.62 eV.
The cobalt catalyst maintains its activity for over 350 hours without deactivation, representing a major improvement in lifespan for ammonia synthesis methods.
This approach to mechanochemical synthesis of ammonia under ambient conditions has potential to reduce carbon emissions compared to traditional methods.
