Inverse kinetic isotope effect of ammonia decomposition over Ru/CeO2 using deuterated ammonia

Takuya Suguro et al. Chem Commun (Camb). .

Abstract

This study investigated the ammonia decomposition mechanism over Ru/CeO2. Isotopic tests using ND3 revealed that the rate-determining step involves adsorbed nitrogen atoms on Ru. Moreover, an inverse kinetic isotope effect where ND3 decomposition was faster than NH3 was clearly observed. The origin of the inverse effect was explained by the lower D coverage on the catalyst surface compared to H coverage for mitigating the inhibition of ND3 activation.
