Abstract

We report the synthesis of Co-Mo alloy nanoparticles with a uniform distribution of the alloy elements on CeO₂via sodium naphthalenide-driven reduction. The resulting sample functions as a highly efficient and stable catalyst for ammonia synthesis. Based on the metal weight, the catalytic activity is ca. 20 times higher than that of Co₃Mo₃N.
