Ammonia synthesis from nitrogen and water at intermediate temperatures and elevated pressures by using an electrochemical hydrogen-membrane reactor with supported Ru catalysts and phosphate electrolytes

A novel electrochemical hydrogen-membrane reactor system was examined to synthesize NH3 from N2 and H2O using electrical power, which enables the conversion of redundant electricity to ammonia as a chemical fuel.

Dissociation Step

The rate-determining step for ammonia synthesis over Ru catalysts supported by electrides, such as [Ca24Al28O64]4+(e−)4 and Ca2N:e−, is suggested to be the surface reactions of N and H adatoms, in which case the Langmuir–Hinshelwood model should be used to describe the kinetics.
