The rate-determining step for ammonia synthesis over Ru catalysts supported by electrides, such as [Ca<sub>24</sub>Al<sub>28</sub>O<sub>64</sub>]<sup>4+</sup>(e<sup>−</sup>)<sub>4</sub> and Ca<sub>2</sub>N:e<sup>−</sup>, 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.
