Abstract:
Cs-Loaded MgO, a typical type of solid superbase, was used as a support to disperse and anchor Ru nanoparticles. Much enhanced Ru dispersion together with electron donation of Cs-loaded MgO enables Ru nanoparticles on Cs-loaded MgO to exhibit excellent activity and intrinsic activity for ammonia synthesis, superior to the conventional Ru/MgO catalyst and the state-of-the-art Cs modified Ru/MgO catalyst under identical reaction conditions.
